cell wall
|
in plant cells; it is the outer most layer, and is composed of cellulose; it's function is to protect and support the cell
|
|
cell membrane
|
found in plant and animal cells
plant - inside cell wall animal- outer layer; cholesterol its selectively permeable |
|
nucleus
|
in both plant and animal
its large and oval controls cell activities |
|
nuclear envelope/membrane
|
plant and animal
it surrounds nucleus, and is selectively permeable it controls movement of materials in and out of the nucleus |
|
cytosol and cytoskeleton (cytoplasm)
|
both plant and animal
cytosol - clear, thick, jellylike material and organelles found inside cell membrane cytoskeleton- network of proteins, fibers, and microtubles supports and protects cell organelles |
|
endoplasmic reticulum (er)
smooth er without ribosomes rough er with ribosomes |
both plant and animal
network of tubes or membranes carries materials through cell, synthesizes lipids, and regulates calcium |
|
ribosome
|
both plant animal
small bodies free or attached to ER produces proteins |
|
mitochondrion
|
both plant and animal
bean shaped with inner membranes breaks down sugar molecules into energy |
|
vacuole
|
plant- few/large
animal - small fluid-filled sacs store food water waste (plants need to store large amounts of food) |
|
lysosome
|
plant- uncommon
animal- common small, round, with a membrane breaks down larger food molecules into smalled molecules digests old cell parts |
|
chloroplast
|
plant only
green, oval usually containing chlorophyll uses energy from sun to make food for the plant (photosynthesis) |
|
chromosomes
|
plant and animal
DNA and proteins found in the nucleus - only seen during cell reproduction carries genetic information from parent cells to daughter cells |
|
nucleolus
|
plant and animal
small sphere inside the nucleus made mostly of RNA helps to make ribosomes for the cell |
|
golgi bodies/apparatus
|
plant and animal
series of flattened stacks of membranes packages and processes chemicals/proteins also makes lysosomes and vesicles |
|
centrioles
|
anot only
small microtubles only seen during cell divison helps move chromosomes during animal cell division |
|
cilia/flagella
|
animal cells (mostly)
rarely in plant cells cilia - numerous short, hairlike ; can be in the thousande flagella- long, whiplike, less than cilia (both) contain microtubles function is for cell movement (human sperm cells) |
