While humans are made up of animal cells and oak trees are made up of plant cells, they both share many organelles that maintain homeostasis for the cell. They also both require energy and contain DNA. ribosomes vacuoles Central vacuole * maintains shape Page 20 E.R. Golgi body lysosomes Cell wall (the outer one) mitochondria chloroplasts Cell membrane animal plant 1. Cell wall- made of cellulose, supports and protects the cell 2. Chloroplasts- site of photosynthesis, uses solar energy to produce energy rich compounds (sugars) and oxygen 1. Nucleus- contains hereditary material (DNA found here), controls most cell activities 2. Ribosomes- site of protein synthesis 3. Vacuoles- stores water and waste 4. Mitochondria- site of cell respiration, releases energy (ATP) for the cell’s metabolic activities 5. Cell membrane- selectively regulates the passage of materials into and out of the cell (compared to the human excretory system) 6. E.R.- transports material 7. Cytoplasm- jell-like, contains organelles, where cellular chemical rxns occur 8. Golgi body- packages and sorts proteins into vesicles Page 22 chloroplasts nucleus mitochondria chlorophyll, photosynthesis, makes energy rich molecules using solar energy Brain of the cell, control center, DNA, contains hereditary info. Energy released/made, cellular respiration, found in greater #’s in active cells, ATP E.R. transport ribosomes protein synthesis vacuoles Storage (water and waste) cell membrane Semi-permeable, selectively regulates the passage of materials cell wall Structure and support, cellulose lysosomes Digestion, enzymes Golgi body Vesicles, sorts and packages cytoplasm Cell metabolic reactions (happens here), jell-like
