Cell Organlle
One difference between prokaryotes and eukaryotes is that
prokaryotes have no nuclear membrane
The Golgi apparatus is an organelle that
receives proteins and lipids from the endoplasmic reticulum. labels the molecules made in the endoplasmic reticulum with tags that specify their destination. releases molecules in vesicles.
Which of the following is a function of the cell membrane?
regulates the movement of materials into and out of the cell
Which organelle makes proteins using coded instructions that come from the nucleus?
ribosome
Which structure makes proteins using coded instructions that come from the nucleus?
ribosome
Which of the following is a function of the nucleus?
stores DNA controls most of the cell's processes contains the information needed to make proteins
The packaging and distribution center of the cell is the
Golgi apparatus.
Which of the following is a function of the cytoskeleton?
helps a cell keep its shape
Which of the following is NOT a function of the cytoskeleton?
helps code for proteins
The cell part that controls most of the cell's activities is the ____.
nucleus
Which cell structure contains the cell's genetic material and controls many of the cell's activities?
nucleus
A structure within a cell that performs a specific function is called a(n)
organelle.
Which of the following best describes the relationship between the nucleus and the cytoplasm?
The nucleus is an organelle that is surrounded by the cytoplasm
The cell membrane
encloses the contents of a cell. allows material to enter and leave the cell. is selectively permeable.
One important organelle that helps maintain homeostasis by moving supplies (proteins, lipids, etc.) from one part of the cell to the other is the
endoplasmic reticulum.
Which of the following enclose their DNA in a nucleus?
eukaryotes
Which organelle breaks down compounds into small particles that the cell can use?
lysosome
Which organelle breaks down organelles that are no longer useful?
lysosome
A particularly active cell, that uses a lot of energy, might contain large numbers of
mitochondria
Which of the following cell parts have similar or related jobs?
mitochondria and chloroplasts
