organellies
cell structures that have specific functions within a cell
plant's cell wall
a rigid layer that surrounds the cells of plants
Animal's cell membrane
controls which substances can enter or leave the cell. these are made of lipids(fats)
plants have a ____________ on the inside of their cell wall
cell membrane
nucleus
a cells control center : directs all cell activity
chromatin-
contains information for directing cell's functions
ribosomes
small grain shaped: produces protein
cyptoplasm
fills the region between the cell membrane and nucleus
mitochondria
converts energy stored into food energy; known as the powerhouse of the cell
endoplasmic reticulum (ER)
located near the nucleus; helps make proteins with ribosomes
Golgi Apparatus
receives proteins from the ER and packages and distributes them to other parts of the cell or outside
vacuoles
a sac that stores water, food, or other materials
lysosomes
contains substances that break down large food particles into smaller ones, also similar to recycling centers
Plants:
have the same organelles as animal cells, but they have a few extra
chloroplasts
(only for plants)captures energy from sunlight and uses it to make energy(food)
in multicellular organisms, how are cells organized
into tissues, organs, and organ systems
tissue
a group of similar cells that work together to perform a specific function
organ
made of different tissues that function together
organ system
a group of organs that work together to perform a major function
