biology task 1 Flashcards
cell membrane
a semipermeable substance that surrounds the cell, only allowing some things in
cell wall
separator of the interior and exterior of the cell providing support and protection
central vacuole
filled with water
helps maintain pressure in the cell and keeps it firm
chloroplast
absorbs sunlight with a fluid called chlorophyll as part of photosynthesis
cytoplasm
the jellylike material that holds every organelle in the cell and protects them
endoplasmic reticulum
3
makes proteins and lipids for the cell
regulates calcium in muscles
detoxifies poison alcohol and drugs
golgi bodies

creates mucus
mitchondria

nuclear membrane
acts as a barrier that separates the content of the nucleus from the rest of the cell
nucleolus
produces and assembles ribosomes
nucleus
controls many parts of the cell by controlling protein synthesis
ribosomes
use protein synthesis to make protein for the cell
vacuole
handles waste within the cell
