Cell Transport (Active and Passive Transport)

Match the function to the organelle.

Groups:

(a) DNA

,

(b) Cytoplasm

,

(c) Ribosomes

• Make proteins

• Gel-like fluid that helps support the cell

• Genetic material of the cell, found in the nucleus

The main difference that distinguished a prokaryote from a eukaryotes is the presence of -

• cell wall
• chloroplasts
• mitochondria
• nucleus

What word best describes homeostasis? ​ (a)  

• stable
• biomolecule
• dynamic
• protein

The cell membrane is found in __________.

• ALL CELLS

• Eukaryotes

• Prokaryotes

• None

The main function of the cell membrane is to -

• provide structural support to the cell
• regulate/control the movement of substances in and out of the cell

• store genetic information
• generate energy for cellular processes

What biomolecules is the primary biomolecule found in the cell membrane? (HINT: its made of a phospholipids bilayer)

• Lipids

• Carbohydrates
• Proteins
• Nucleic acids

Molecules that can simply pass through the cell membrane are said to go through a specific type of passive transport, which is​ (a)   . This process ​ (b)   require energy to take place.

• simple diffusion
• does NOT
• osmosis
• facilitated diffusion
• does

Passive transport is said to move with the flow. This means - (SELECT TWO ANSWERS)

• going WITH the concentration gradient

• going AGAINST the concentration gradient

• moving from LOW concentration to HIGH concentration

• moving from HIGH concentration to LOW concentration

Passive transport moves from ​a​ (a)   concentration of molecules, to a ​ (b)   concentration of molecules.

• HIGH
• LOW

The main difference between simple diffusion and facilitated diffusion is that facilitated diffusion requires the presence of ____________.

• ion channels
• cell membranes
• energy input
• transport proteins
