cell bio

what is the function of mitochondria?

site of aerobic respiration, releases energy

name 3 structures found in plant cells but not animal cells

Cell wall, chloroplasts, large central vacuole

what is the formula for magnification

The formula for magnification is the size of the image divided by the size of the actual object.

what is the role of the nucleus

The nucleus serves as the control center of the cell, housing the cell's genetic material (DNA) and coordinating activities like growth, metabolism, and reproduction.

what is mitosis used for

Mitosis is used for cell division, growth, and tissue repair in organisms.

what is the function of stem cells

Stem cells have the ability to differentiate into various types of cells and can self-renew, playing a crucial role in development, repair, and regeneration of tissues.

define osmosis

define active transport

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration using energy, usually in the form of ATP.

define diffusion

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.

define differentiation and state which cells go through this

Differentiation is the process by which a less specialized cell becomes a more specialized cell type, such as stem cells differentiating into muscle or nerve cells.

how does root hair cells differentiate

Root hair cells differentiate from meristematic cells, developing specialized structures that increase surface area for water and nutrient absorption.

how does stem cells differentiate

Stem cells differentiate into specialized cell types, such as blood cells, nerve cells, or muscle cells, through a series of controlled developmental stages.

whats the function of muscle cells

Muscle cells are specialized for contraction and movement, enabling the body to perform various physical activities. They can be categorized into skeletal, cardiac, and smooth muscle types, each serving distinct functions.
