Unit 2: Ch7 Flashcards
Compare and contrast animal and plant cells
Animals: Lysosomes Many small vacuoles Centered nucleus Rounded Centrioles
Plants: Chloroplasts Cell walls One large central vacuole Nucleus to the side Rectangularish
Both: Mitochondria Eukaryotic Ribosomes Endoplasmic reticulum Vacuoles Nucleus Cell membrane Cytoplasm Golgi apparatus
Why is it important for cells to have semipermeable membranes?
Allows only certain substances to enter and leave the cell
What organelle is considered the powerhouse of the cell bc it produces ATP through cell respiration?
Mitochondria
What organelle is only found in plant cells and algae and converts energy from the sun into energy?
Chloroplasts
What organelle has its own DNA and provides energy to plant and animal cells?
Mitochondria
Define mitochondria
Organelle is considered the powerhouse of the cell. ATP is made here
Define cytoskeleton
System of microtubules helps support the cell and gives it structure
Define chloroplasts
Found in plant cells converts sun light into energy
Define lysosomes
Helps break down waste and materials
Define central vacuole
Found in plant cells
Holds water
Define ribosomes
Where proteins are made
Define nucleus
Directs cell activities
Holds DNA
Where DNA replication occurs
Define endoplasmic reticulum
Extensive system of internal membrane s that move proteins through the cell
Define Golgi apparatus
Flattened membrane bound sacs that serve as the packing and distributing center
Define nuclear membrane
Allows certain molecules to enter and leave the NUCLEUS
What type of cells in the body would have more mitochondria?
Muscle cells; this is where cellular respiration occurs
Define vesicle
Small Membrane bound sac that transports substances
