What are cells that are alike in size shape and function called quizlet?
Multicellular organisms are composed of many different types of cells. Cells grouped together according to their similarity in shape, size, structure, intercellular materials, and functions are called tissues. Protects the body by covering internal and external surfaces. You just studied 48 terms!
What is the shape and size of cells related to?
The size and shape of a cell are related to its function and are governed by four factors—(1) surface-volume ratio, (2) nucleocytoplasmic ratio, (3) rate of cellular activity, (4) cell associations. (1) Surface-volume Ratio: ADVERTISEMENTS: The cell membrane separates the inner content from the outer environment.
What is a group of similar cells with same kind of function called?
tissue
A group of similar cells organized to perform a particular function is a “tissue.”
Why do cells differ in size shape and function?
Cells have different shape and size because different cell types have different functions. For example : Red blood cells are shaped like a doughnut to carry more hemoglobin, and to fit through small spaces, and neurons are long and skinny to span wide places to send signals around the body .
What type of tissue is in bone?
Tissue that gives strength and structure to bones. Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts.
How are the size and shape of a cell related?
The size and shape of a cell are related to its function and are governed by four factors—(1) surface-volume ratio, (2) nucleocytoplasmic ratio, (3) rate of cellular activity, (4) cell associations.
What are the two types of cells in a multicellular body?
The cells in a multicellular body are of two types, germ cell and somatic cell. The cells which are only responsible for reproduction are called germ cells and the remaining cells are called somatic cells. Similarly, shape and size of the cells also vary extensively (Fig. 4.16).
Which is more active a cell or a smaller cell?
The more active cells are usually smaller and in them, the surface- volume ratio and nucleo-cytoplasmic ratio are in such a level that these cells can work more actively than the larger cells. The cell-to-cell attachment is important in multicellular forms which render some amount of rigidity.
What kind of cells are responsible for reproduction?
The cells which are only responsible for reproduction are called germ cells and the remaining cells are called somatic cells. Similarly, shape and size of the cells also vary extensively (Fig. 4.16). Some multicellular forms (Rotifers) may be smaller in size than many unicellular forms, i.e., Amoeba, Spirostomun, etc.
