What part of a cell holds water? Which of the following plant cells has strong turgor pressure? How does turgor pressure affect a plant?

01.14.13 Intro to Cells VideoWe will learn about cells and their specific functions by watching a video.

S-

Cell A Cell B Cell CVacuole

P - Read the TEK what is the main idea you need to know for each bulleted point:

• The student knows that living systems at all levels of organization demonstrate the complementary nature of structure and function. The student is expected to:

• (D) differentiate between structure and function in plant and animal cell organelles, including cell membrane, cell wall, nucleus, cytoplasm, mitochondrion, chloroplast, and vacuole;

• (E) compare the functions of a cell to the functions of organisms such as waste removal; and

• (F) recognize that according to cell theory all organisms are composed of cells and cells carry on similar functions such as extracting energy from food to sustain life.

Complete the worksheet while we watch! A

Explain why all of these statements are true using evidence from the video…

C -

1. Each cell has a specific function within an organism.

2. Plant cells differ from animal cells in structure and function.

3. The shape of a cell is directly related to the function of that cell.
