protein

One of the main functions of the semi-permeable cell membrane is to maintain homeostasis for the cell. Semi-permeable means that only some molecules are allowed to cross the membrane and others are not.

Which biomolecule molecule enables large molecules to cross the membrane?

Both prokaryotes and eukaryotes have small, free-floating organelles. The cell makes these organelles from nucleic acids and amino acids found in food. Without these organelles, the cell could not make proteins.

These organelles are called ​ (a)  

• ribosomes
• nucleus
• cell membrane
• mitochondria
• chloroplast

Match the cell structure with its primary function.

Move the correct answers to the correct boxes.

​ (a)   - controls cell activities

​ (b)   - protein synthesis

​ (c)   - controls what goes in and out of the cell

​ (d)   - support

​ (e)   - provides energy for the cell

• nucleus
• ribosome
• cell membrane
• cell wall
• mitochondrion

Which type of movement across a cell’s plasma membrane requires energy supplied by ATP?

• Passive Transport

• Simple Diffusion

• Active Transport

• Osmosis

Passive transport is represented in three different forms. ​ (a)   is the movement of water across a semipermeable membrane. ​ (b)   , like when someone sprays perfume, is the movement of molecules down or under a concentration gradient. ​ (c)   is the movement of molecules down a gradient with the help of special protein channels.

• Osmosis
• Diffusion
• Facilitated Diffusion
• Active Transport
