Intro to Cells Re-Teach Fall 2022

Multiple Choice

A membrane (lipids) bound organelle that takes in nutrients (carbohydrates) and breaks them down to create energy for the cell.

• Chloroplast

• Golgi Body

• Mitochondrion

• Endoplasmic Reticulum

Multiple Choice

Receives biomolecules (proteins) from the Rough Endoplasmic Reticulum and packs them into sealed droplets called vesicles (lipids) ready for delivery.

• Chloroplast

• Golgi Body

• Mitochondrion

• Endoplasmic Reticulum

Multiple Choice

Membrane (lipids) bound organelle that contains chlorophyll pigments which absorb sunlight and uses it to make food (carbohydrate) by performing photosynthesis.

• Chloroplast

• Golgi Body

• Mitochondrion

• Endoplasmic Reticulum

Multiple Choice

Membrane (lipids) bound organelle that regulates ions and processes toxins.  Also includes membrane (lipids) bound organelle studded with ribosomes (Nucleic acids) for creating catalysts (proteins).

• Chloroplast

• Golgi Body

• Mitochondrion

• Endoplasmic Reticulum

Fill in the Blanks

Strong structural string-like filaments (proteins) that give the cell its shape.

*Function varies with the type of cell in which they are present.  Membrane (lipids) bound organelle that is used for storage, water balance, structure, etc.

Fill in the Blanks

Located in the nucleus and is responsible for assembling rRNA (Nucleic Acids) into ribosome organelles.

Fill in the Blanks

Membrane (lipids) bound organelle that contains enzymes (proteins) that can break down biomolecules and gets rid of wastes.

Fill in the Blanks

The liquid inside the cell around the organelles.

Fill in the Blanks

Small organelle (Nucleic Acids) that uses DNA organelle (Nucleic Acids) instructions to make catalysts (proteins) for the cell.

Fill in the Blanks

Membrane (lipids) that is a semi-permeable barrier to separate the cell from the outside environment.

Membrane (lipids) that is a semi-permeable barrier to separate the cell from the outside environment.

Open Ended

The presence of hydrolytic digestive enzymes is most closely associated with cell organelles known as lysosomes. Explain what "lyse" means in science and how it is related to both hydroLYSis and LYSosomes.

​Centrioles

Centrioles are found in animal cells.

Centrioles are used for animal cells to reproduce. They release long, stiff fibers called microtubules that split the cell apart during cell division. Watch this video.

​

​

First cells on our planet were prokaryotic bacteria. They were small, simple and lacked organelles. They were simply DNA and ribosomes floating in cytoplasm surrounded by a membrane and cell wall.

Prokaryotes

​The endosymbiotic theory attempts to explain how eukaryotes evolved from prokaryotes. These cells are larger, more complex and contain membrane bound organelles like a nucleus.

Eukaryotes​

​

Viruses are NOT cells. They are genetic material surrounded by a protein shell. They can evolve and are considered "non-living infection particles". They do not reproduce on their own, grow, need food, or maintain homeostasis.

Viruses

The mitochondria organelle converts chemical energy in glucose into usable energy (ATP). The mitochondria is found in BOTH animal and plant cells. Explain how you know that this organelle is found in Eukaryotes and NOT prokaryotes:

Fill in the Blanks

Centrioles aid in separating DNA during cell division of some eukaryotic cells. Which types of eukaryotic cells contain centrioles?

Open Ended

The nucleus organelle controls cellular activities and can be found in both plants and animal cells. Explain how you know that this is found in Eukaryotes and not Prokaryotes.

Open Ended

The presence of hydrolytic digestive enzymes is most closely associated with cells organelles known as lysosomes. Explain what the root word 'lyse' means and how it relates to hydroLYSis and LYSosomes.
