what are the parts that make up a cell
Cytoplasm, nucleus, chromosomes, vacuole, cell membrane
What are the 3 example of unicellular organism
- bacteria
- protisis
-some fungi
What is cell differentiation/ specialization
The process of how a cell becomes a specific cell perform a task.
What is a selectively permeable membrane
a membrane that allows only certain substances to pass through it
What are the 3 things stated by cell theory
- All living things are made up of cells
- The cell is the basic unit of life
- All cells come from pre-existing cells
What do vacuoles do
Vacuoles are cells Storage: food, water and waste
what are the 3 ways unicellular eat
by eating other organisms
by working with other organism
Through photosynthesis
a tissue is a group of cells the work together to do a specific task
a organ is a group of tissues that work toothier
What is the diffusion
the movement of particles from an area of higher concentration to an area of lower concentration
what is the magnification power of each objective lens on a microscope
low-power lens = 4x
medium-power lens = 10x
high-power lens = 40x
Why do only plant cells have a cell wall.
To help keep the plant rigid and upright.
what is gas exchange
gas exchange is when oxygen passes in to the cell through division and co2 goes out of the cell through diffusion
What are the basic needs of a multicellular organism
Nutrition, gas exchange, responding to the environment, movement and locomotion
What's the difference between osmosis and diffusion
Diffusion is the general term and osmosis is specific to cells
what's a compound microscope
a compound microscope is a microscope the compounds lenses to help you see the specimen
What are the 3 main differences of plant and animal cells
Only plant cells have a cell wall and chloroplast and can't have flagella or cilia like animal cells
what is the most common type of unicellular organism
bacteria
What are the 5 systems that make up most animal bodies
nervous systen circulatory system respiratory system digestive system musculoskeletal system
what dose turgor pressure
when there is water in the cell and it pushes agents the cell wall to make the cell rigid. only in plant cells
what are the 7 characteristics of living things
grow, reproduce, can repair themselves, need energy/food, respond to changes in the environment, have a lifespan and produce waste.
why do animal cells have flagellum and cilia but plant cells don't
animal cells need to move to get their food while plants don't
where do unicellular organism usually live
in water
what are the two organ systems of plants
the shoot and the root
what is a concentration gradient
(bouns) how dose diffusion and concentration gradient work together
a concentration gradient is a difference in concentration over an area
Diffusion works in a concentration gradient by taking the particles of high concentration in the gradient and moving them to low concentration in the gradient
what do the xylem and phloem vessels do
the xylem brings water and minerals to the leaves for photosynthesis and the phloem brings the food made after photosynthesis to the rest of the plant
