Where do nearly all living things get their energy (directly or indirectly) from?
Nearly all living things obtain energy either directly or indirectly from the energy that is captured during photosynthesis.
100
Where does cellular respiration happen in the cell?
Cellular respiration occurs in mitochondria.

What does cell division allow organisms to do?
Cell division allows organisms to grow, repair damaged structures, and reproduce.

Explain the difference between autotrophs and heterotrophs, and give an example of each.
Autotrophs produce their own food, like a sunflower. Heterotrophs eat other organisms for energy, such as cows.

Explain why dough rises and expands over time.
The yeast in dough eats the flour and releases carbon dioxide through the process of fermentation, causing the dough to rise.

What is it called when DNA is copied?
Replication

In which part of the plant cell does photosynthesis occur? And what is the pigment that gives plants their green color?
Photosynthesis happens inside of chloroplasts, which contain chlorophyll and give plants their green color.

Explain the difference between fermentation and cellular respiration. When are each of them used?
Cellular respiration is when cells break down glucose and other molecules from food in the presence of oxygen, releasing energy. This constantly happens in our cells. During fermentation, cells release energy from food without using oxygen. This gives less energy. One example is when yeast ferments bread dough or alcohol.

What happens during the cell cycle?
A cell grows, prepares for division, and divides into two new cells, which are called daughter cells.

Give an example of a realistic four organism food chain
Ex - Grass --> Rabbit --> Snake--> Hawk

How are photosynthesis and cellular respiration similar? How are the different?
Cellular respiration and photosynthesis are like opposite processes. Photosynthesis uses light energy, carbon dioxide, and water to make glucose and oxygen. Cellular respiration does the opposite and uses glucose and oxygen to make carbon dioxide, water, and energy.

What are the three stages of the cell cycle? Briefly explain each one.
1. Interphase - Cell grows, copies DNA, and prepares to divide.
2. Mitosis - Cell's nucleus divides into two nuclei, and DNA is split up between them.
3. Cytokinesis - Cytoplasm divides and cell division is completed

What is the equation for photosynthesis? (include the numbers) What are the raw materials of photosynthesis? What are the products in photosynthesis?

What is the equation for cellular respiration? (include the numbers) What are the raw materials of cellular respiration? What are the products of cellular respiration?

What are the four phases of mitosis? Briefly explain each one.
1. Prophase - chromosomes (DNA) condense and nucleus breaks down.
2. Metaphase - Chromosomes line up in middle of cell and attach to fibers
3. Anaphase - Chromosomes are drawn to opposite ends of the cell and DNA is divided.
4. Telophase - Two new nuclei form with chromosomes (DNA) inside of them.
