Cells
What are cells?
A basic unit of an organism.
Dose eukaryotic cells have a nucleus?
Yes
Basic unit of an organism.
Cells.
What does the cytoplasm do?
Liquid part of cell inside the cell membrane, jelly-like, mostly water (all cells).
Can heterotrophs make food?
No.
What are 3 things cells have to do to be alive?
grow and develop.
reproduce (asexual & sexual).
respond to their environment (stimuli).
use energy (autotrophs and heterotrophs).
organized (need nutrients).
made of cells.
What are 2 similarities between a eukaryotic and prokaryotic cell.
They both have a cell membrane. They both have ribosomes. They both have cytoplasm. They both have DNA / genetic material
A strong, rigid layer outside of the cell membrane (plants, fungi, some bacteria).
Cell wall.
What does the cell membrane do?
Forms a boundary between the cell and the environment, controls movement of substances in and out.
Do autotrophs make food?
Yes.
Does a prokaryotic or eukaryotic have a nucleus.
Eukaryotic.
What are 2 differences between a eukaryotic cell and a prokaryotic cell.
Prokaryotic cells do not have a nucleus or other membrane bound organelles (Eukaryotic cells do have nucleus & organelles)
Prokaryotic cells are simpler and eukaryotic are more complex
Most eukaryotes are multicellular (All prokaryotes are unicellular)
Eukaryotes are generally bigger (Prokaryotes are generally smaller)
A specific environment where an organism lives (Home)
Habitat.
What is the Binomial nomenclature.
A two-word naming system that gives each living thing a scientific name (genus & species)
What are autotrophs mostly in what?
Plants.
70% of cells are made of what?
Water.
What is 1 things eukaryotic cells have that prokaryotic cells don't have?
Nucleus.
Stores food, water, and wastes. (BIG in plants, may be in animal cells)
Vacuole.
What does the cell wall do?
Help plants to not fall.
How do autotrophs make food?
They convert light.
Are cells the simplest or the most complex out of these(tissues, organ systems, cells, organs).
Simplest.
What is 1 things prokaryotic cells are that eukaryotic cells are not?
Simpler.
Organelles that break down food and release energy during respiration (powerhouse)
Mitochondria.
What reproduction is with one parent?
Asexual.
What do hetertophs eat?
Autotrophs.
