Bio: Cells

What type of cell is this?

• prokaryotic

• eukaryotic

• hypertonic

• plant

Which phrase describes the cell membrane?

• rigid wall

• solid brick model

• completely permeable

• fluid mosaic model

The nucleus, ER, ribosomes and Golgi all work together to

• make and secrete proteins

• build and release sugar

• make energy for the cell

• make new organelles

Endocytosis, exocytosis, and protein pumps are examples of

• passive transport

• organelle production

• active transport

• metabolism

The cell membrane is selectively permeable which means

• it lets everything pass through freely

• it only lets nonpolar molecules pass through

• only some molecules can pass through freely

• nothing can pass through without help

What are the functions of the cell membrane?

• to keep everything out of the cell

• to form the cell boundary

• to let everything come inside

• to make proteins

• to control what enters and leaves the cell

What are the principles of cell theory?

• all cells come from other cells

• cells are the smallest unit of life

• all living things are made of 1+ cells

• cells can arise spontaneously

• all living things are made up of more than one cell

This type of cell has a nucleus and membrane-bound organelles

• prokaryotic

• eukaryotic

• bacterial

• hypertonic

Which organelles are found in plant cells but not (typically) in animal cells?

• mitochondria

• nucleus

• cell wall

• chloroplasts

• cell membrane

Phospholipids are made up of

• polar head, nonpolar fatty acid tails

• polar head, polar fatty acid tails

• nonpolar head, nonpolar fatty acid tails

• nonpolar head, polar fatty acid tails
