Specialized structures that work together inside a cell.
What are organelles?
Which best describes the nuclear membrane:
a) It is rigid and impermeable
b) It is identical in composition to the cell membrane
c) It allows all molecules to pass across it into the nucleus.
d) It contains pores that allow only certain molecules to pass.
What is answer choice d?
A rigid layer that gives protection, support, and shape to a plant cell.
What is a cell wall?
The most basic unit of life.
What is a cell?
T/F Eukaryotes have more complicated cells than prokaryotes and can only be multicellular.
What is False?
These organelles can be found in the cytoplasm and on the surface of the ER?
What are ribosomes?
An organelle that carries out photosynthesis in plant cells.
What is a chloroplast?
This is the powerhouse of the cell.
What is the mitochondrion?
T/F Prokaryotes have simpler cells than eukaryotes and can be either unicellular or multicellular.
What is false?
A membrane-bound sac used to transport substances into and out of cells.
What is the vesicle?
A structure unique to plant cells that is filled with a watery fluid that strengthens the cell and supports the entire plant.
What is the central vacuole?
This controls the movement of materials into and out of the cell.
What is a cell membrane?
Explain the relationship between cells, organs, and tissues.
What is cells that are similar form tissues to perform specific functions and different tissue types combine to form organs?
The structure of the human skin cell differs from that of the muscle cell because they have different:
a) genes
b) functions
c) life processes
d) ways of dividing
What is different functions?
These three organelles work together to produce, process, sort, and deliver proteins?
What are the ER, ribosomes, and the Golgi apparatus?
A group of similar cells that work together to perform a specialized function.
What is a tissue?
Name three organ systems.
What are: Circulatory; Digestive; Endocrine; Excretory; Immune; Integumentary; Muscular; Nervous; Reproductive; Respiratory; or Skeletal?
This is where human cells get most of the energy they need for metaboism.
What is the food you eat?
These three structures/organelles are found in a plant cell but not an animal cell.
What are the cell wall, chloroplasts, and a central vacuole?
The process by which cells become specialized in structure and function.
What is cell differentiation?
