What are the four characteristic of living things
Growth, reproduction, response to environment, and uses energy
What is the difference between a prokaryotic organism and a eukaryotic organism? Give an example of each
Eukaryotic organisms have membrane bound and nucleus and prokaryotic organisms do not
Eukaryotic-fungi
Prokaryotic-Algae
nucleus
control all cell activities and hold the DNA of the cell.
Vacuole
stores water and maintains water pressure.
List three structures that are found in plant cells but not animal cells
cell wall, vacuole, chroloplast.
What is a cell
The smallest unit that can live on its own and that makes living organisms and the tissues of the body.
Can a eukaryotic organism ever be a unicellular organism?
They can be unicellular organisms.
Golgi Apparatus
Sorts and packages throughout the cell
Cell wall
provide shape and support for plant.
What do immune cells in a human do? Do immune cells do the same thing as brain cells?Why or why not?
The immune system cells respond to injuries to help repair or get rid of bad bacteria. Immune cells do not do the same thing as brain cells because each type of cell in multicellular organism are specialized and have different functions.
What do we mean when we say cells are microscopic
It means that they are really small and can only be seen by a microscope
Plasma Membrane
selects which molecules enter/exit the cell
Endoplasmic recticulum
produce lipids and transport protein
Chloroplast
site of photosythesis
Why do cells communicate in multicellular organisms.
allows for specialization of groups of cells.
What are three parts of cell theory
1-All living cells came from existing cells
2-A cell is a basic structural and functional unit of living organisms
3-All living organisms are made from one or more cells.
cytoplasm
hold organelles in place
Lysosomes
digest/recycles food or worn out cell parts
What is an organelle?Give two example of organelles
Any of a number of organized and specialize structures within a living cell.
Examples-lysosome and nucleus, etc.
What is an organ? Give two example of organs.
A connection of more than two tissue that form a functional unit.
Examples, lungs, heart, kidney, etc.
What is the difference between a unicellular organism and a multicellular organism? Give an example of each
A unicellular is an organism that has only one cell and a multicellular organism has multiple cells.
Unicellular organisms-Bacteria
Multicellular organism-Animal
ribosomes
make protein
Mitochondria
Powerhouse of cell
1-Plasma membrane
2-cytoplasm
3-DNA
4-Ribosomes.
What is an organ system? Give two examples
A biological system formed or organs that work together. Two examples are digestive and circulatory, etc.
