cell theory 1
The first tenet of cell theory
all living things are made of cells
The basic building block of life
cell
Tiny cell structures that perform life functions
organelles
Define chlorophyll
The green pigment in chloroplasts that absorb sunlight energy for photosynthesis
organelle contains cells genetic material and controls cell activity
nucleus
the second tenet of cell theory
cells are the basic building blocks of life
general name for organisms made up of just one cell
unicellular
cells that have a true membrane bound nucleus
eukaryotic
role of the cell membrane
controls what enters and leaves the cell
site of cellular respiration
mitochondria
The third tenet of cell theory
all cells come from preexisting cells
Cell Theory could not be proven until the invention of what tool?
the microscope
cells that have a nucleoid
prokaryotic
Central Vacuoles in plants are larger than Vacuoles in Animal cells. Why?
Plants need larger storage areas since they cannot move freely
plants need help standing upright
Organelles only found in animal cells
lysosomes
centrosomes
general name for organisms made up of many cells
multicellular
Identify Schleiden's discovery
Identify Schwann's discovery
schleiden- all plants are made of cells
schwann- all animals are made of cells
manufactures and transports mostly lipids
smooth endoplasmic reticulum (Smooth ER)
organelles which work together to provide energy for the plant cell
chloroplast
mitochondria
Explain what would happen if more mitochondria were added to a cell
The cell would create more energy
Explain why it is false that an organism grows because the cells become larger
A growing organism has dividing cells; not cells that get larger
Certain cells undergo mitosis. Mitosis is cell division. Which part of Cell Theory does mitosis belong to?
all cells come from preexisting cells
Compare and contrast animal and plant cell vacuoles
both used as storage
animal cell- small and many
plant cell- one large central vacuole
Organelles found only in plant cells
chloroplast
cell wall
central vacuole
How does the cell membrane assist mitochondria in producing energy
It allows materials into the cell to help mitochondria create energy
