Cell theory
cell
Which organelle controls material exchange ina cell
cell membrane
What organelle is responsible for food production in a plant cell
chloroplast
What is the purpose of mitosis
Growth and repair
Which process does not require energy?
1.Osmosis
2. Active Transport
3. Diffusion
4. Osmosis AND Diffusion
Neither Osmosis nor diffusion requires energy. These are passive transport
Which of the following is NOT part of the Cell theory?
1. all living things are composed of cells
2. Cells are the basic unit of life
3. cells arise from non-living material
4. All cells come from pre-existing cells
cells arise from nonliving material
What is the primary function of mitochondria
Energy production
What organelle is similar to a cell wall but is in BOTH animal and plant cells
cell membrane
The purpose of meiosis is to...
create reproductive cells
What does active transport require
energy
Which tool advanced the understanding of cells
microscope
what is the main purpose of the vacuole in plant cells?
material/water storage
True or false: Both plant and animal cells have a cell wall
False. Only plant cells
What phase of mitosis involves chromosomes lining up in the center of the cell?
metaphase (Think M for middle)
What phase of the cell cycle involves growth and DNA replication?
Interphase. The beginning, to copy the DNA first in order to create a new cell. JUST think INTER comes first like you ENTER a room.
What is the basic unit of life
cell
what is the primary role of ribosomes
synthesize proteins
What organelle is responsible for photosynthesis
chloroplast
Mitosis results in....
two identical cells
What is the process of moving water across a membrane
osmosis
Who coined the term cell
Hooke
cell membrane is responsible for what
controlling what enters and exits the cell
Why do plants need a cell wall
meiosis results in ....
4 haploid cells
("hap" like "half" because this is from sperm and egg)
The process of moving substances from a high to low concentration is called....
Diffusion
