Ehrlich noted certain dyes would color human, animal, or bacterial cells, while others did not.

Most plant and animal cells are between 1 and 100 µm and therefore are visible only under the microscope.

* Lysosome-break down cellular waste products and debris into simple compounds ( only found in animal cells )

Centrioles were previously thought to be required for the formation of a mitotic spindle in animal cells.

The endoplasmic reticulum ( ER ) is a synthesis and transport organelle that branches into the cytoplasm in plant and animal cells.

Vacuoles, which are found in both plant and animal cells ( though much bigger in plant cells ), are responsible for maintaining the shape and structure of the cell as well as storing waste products.

However, other methods exploit natural forms of gene transfer, such as the ability of Agrobacterium to transfer genetic material to plants, or the ability of lentiviruses to transfer genes to animal cells.

Found within the cytoplasm of both plant and animal cells, the Golgi is composed of stacks of membrane-bound structures known as cisternae ( singular: cisterna ).

Nineteenth-century biologists reported that the Hydra was such a simple animal that it was possible to force one through gauze to separate it into individual cells ; if the cells were then left to themselves, they would regroup to form a hydra again.

The glycerophospholipids are the main structural component of biological membranes, such as the cellular plasma membrane and the intracellular membranes of organelles ; in animal cells the plasma membrane physically separates the intracellular components from the extracellular environment.

They are found in animal cells, while their existence in yeasts and plants are disputed.

During these stages, two centrosomes, containing a pair of centrioles in animal cells, migrate to the two poles of the cell.

Cytokinesis, the pinching of the cell membrane in animal cells or the formation of the cell wall in plant cells, occurs, completing the creation of two daughter cells.

In animal cells, the cell pinches inward where the imaginary line used to be ( the area of the cell membrane that pinches to form the two daughter cells is called the cleavage furrow ), separating the two developing nuclei.

Like all animal cells, every neuron is surrounded by a plasma membrane, a bilayer of lipid molecules with many types of protein structures embedded in it.

The nervous system is an organ system containing a network of specialized cells called neurons that coordinate the actions of an animal and transmit signals between different parts of its body.

* The sperm of bryophytes and pteridophytes have flagellae similar to those in animals, but higher plants, ( including Gymnosperms and flowering plants ) lack the flagellae and centrioles that are present in animal cells.

Glycogen serves as the secondary long-term energy storage in animal and fungal cells, with the primary energy stores being held in adipose tissue.

As we think of the long and excruciating pain it must have suffered, we are very likely to say: `` It was a bad thing that the little animal should suffer so ''.

Temperature determines metabolic rates, heart rates, and other very important factors within the bodies of animals, so an extreme temperature change can easily distress the animal ’ s body.

They did not call the animal a bunyip, but described the remains indicating the creature as very much like a hippopotamus or manatee.

At the same time, some settlers observed " all natives throughout these ... districts have a tradition ( of ) a very large animal having at one time existed in the large creeks and rivers and by many it is said that such animals now exist.

His 1852 account records " in ... Lake Moodewarri Lake Modewarre as well as in most of the others inland ... is a ... very extraordinary amphibious animal, which the natives call Bunyip.

As effect of these restrictions the country incorporated very few new crops and animal breeds after initial conquest.

The complex ecology of chaparral habitats supports a very large number of animal species.

Animal costumes which are visually very similar to mascot costumes are also popular among the members of the furry fandom where they are referred to as fursuits that match ones animal persona, or fursona.

The dyes were obtained from animal, vegetable or mineral origin, with no or very little processing.

For example, while burning an area of fairly thick forest and thus turning it into a more open, grassy environment might reduce the viability of a large browser ( an animal that eats leaves and shoots rather than grasses ), the reverse could also be true: removing the browsing animals ( by eating them, or by any other means ) within a few years produces a very thick undergrowth which, when a fire eventually starts through natural causes ( as fires tend to do every few hundred years ), burns with greater than usual ferocity.

Understanding ethology, or animal behaviourism, is very important in animal training.

It should be noted that many animal models are poor substitutes for studying carcinogenic effects in humans because the physiology of rabbits, mice and non-human primates can be very different from humans in the relevant biochemical pathways.

Ammo cans are considered the gold standard of containers because they are very sturdy, waterproof, animal and fire resistant, relatively cheap, and have plenty of room for trade items.

Supporters are human or animal figures or, very rarely, inanimate objects, usually placed on either side of a coat of arms as though supporting it.

" What could have saved Indian society from the ponderous burden of omnifarious ritualistic ceremonialism, with its animal and other sacrifices, which all but crushed the very life of it, except the Jain revolution, which took its strong stand exclusively on chaste morals and philosophical truths?

The volcanic origin and remote location of the islands meant that the islands ' flora and fauna had to reach the archipelago from far across the sea ; as a result, the island is home to relatively few plant species and very few animal species.

It is generally a silent, nocturnal animal, but males have a very loud advertising call that can be heard from almost a kilometre away during the breeding season.

:* Trichoplax adhaerens, a very simple free-living animal from the phylum Placozoa used as a model in evolutionary developmental biology and comparative genomics

A mummy is a body, human or animal, whose skin and organs have been preserved by either intentional or incidental exposure to chemicals, extreme cold ( ice mummies ), very low humidity, or lack of air when bodies are submerged in bogs, so that the recovered body will not decay further if kept in cool and dry conditions.

Over nine-tenths of the total biomass on Earth is plant life, on which animal life depends very heavily for its existence.

Nucleoli of various plant species have been shown to contain very high concentrations of iron in contrast to human and animal cell nucleoli.

Krantz describes Donskoy's conclusion as being that the film depicts " a very massive animal that is definitely not a human being.

Because the red panda is considered a very attractive animal, and is not much larger than a house cat, it would seem to be ideal for a pet.
