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
