What is homeostasis?

The stable internal conditions of a living thing.

Which of the following would NOT be an example of maintaining homeostasis? A. the body temperature staying 98.6 o F B. Blood sugar levels staying at 140 mg/dl C. Dissolved oxygen levels in the blood changing dramatically

C

How does the cell membrane maintain homeostasis?

The cell membrane maintains homeostasis by controlling what enters and leaves the cell.

Draw and label the parts of the cell membrane using the terms: phospholipids, integral proteins, peripheral proteins and cholesterol.

What are the three types of passive transport (diffusion)?

Dialysis Facilitated Diffusion Osmosis

In the following situation only water is small enough to move across the cell membrane. A) Which way will the water move? B) What type of diffusion is this? C)What type of solution is the cell in? (hypotonic, hypertonic, isotonic)

A) Out of the cell B) osmosis C) hypertonic

In the following cell there is glucose which IS a small enough molecule that CAN pass through the cell membrane. A) Which way will the glucose move? B) What type of diffusion is this?

A)Into the cell B) Dialysis

Which Cell will lose the most amount of Water?

A

All of our cells require oxygen, fortunately it is a small molecule that can diffuse across our cell membranes. In the following situation which way will the oxygen move?

Into the cell.

What are the 3 main types of active transport?

Endocytosis Exocytosis Pumps

Is the following picture of Endocytosis or Exocytosis?

Exocytosis

Do the following items describe active or passive transport? A) Requires Energy B) Molecules move from high to low concentration C) Osmosis

A)Active B) Passive C) Passive

Do the following items describe active or passive transport? A) Diffusion B) Molecules move from low to high concentrations C) Endocytosis

A)Passive B) Active C) Active

What is the only molecule that moves in osmosis?

water

What determines the way the water will move in osmosis?

- Water moves from where there is more water to where there is less. - Water moves from where there is less solute to where there is more solute. - Water moves from a hypotonic solution to a hypertonic solution.

What happens to a plant cell if it is placed in a hypertonic environment, be specific – use the terms we’ve used in this unit.

Plasmolysis – the cell membrane pulls away from the cell wall and the plant will wilt and eventually die.

A)Draw a cell that is in a hypotonic environment. B) Will the cell gain or lose mass? C) What types of cells, plant or animal, typically live in a hypotonic environment?

A) B) Gain C) Plant

List the following molecules from the smallest to the largest. Sucrose, starch, glucose and water

Water, glucose, sucrose, starch

The following cells are at the end of the transport process. In which cell did active transport take place and in which did passive transport take place?

Passive transport = A Active transport = B
