Biology: How a cell is build

My sister's project from a few years ago.

organelles - A tiny cell structure that carries out a specific function within the cell.

cell wall - A rigid layer of nonliving material that surrounds the cells of plants and some other organisms.

cell membrane - The outside boundary of a cell; controls which substances can enter or leave cell.

nucleus - The control center of a cell that directs the cell's activates; contains the chemical instructions that direct all the cell's activities and determine the cell's characteristics.

nuclear membrane - It's a membrane protecting a nucleus.

chromatin - Material in cells that contains DNA and carries genetic information.

chloroplasts - A structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food.

My project
vacuoles - A water-filled sac inside a cell that acts as a storage area.

lysosomes - A small round cell structure that contains chemicals that break down large food particles into smaller ones.

nucleolus - A structure in nucleus where ribosomes are made.

cytoplasm - The region of a cell located inside the cell membrane (in prokaryotes) or between the cell membrane and nucleus (in eukaryotes); contains a gel-like material and cell organelles.

mitochondria - Rod-shaped cell structures that produce most of the energy needed to carry out the cell's functions.

endoplasmic reticulum - A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.

ribosomes - A tiny structure in the cytoplasm of a cell where proteins are made.

Golgi bodies - A structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of cell.
