A plant cell that lacks chloroplasts will not

1) give of oxygen
2) take in food
3) give of carbon dioxide
4) take in water

I chose number 2 but when I looked in the answer key it said 1. Could you please explain me why it is number 1 instead of 2.

all cells (plant, animal, etc) have to take in food (nutrients) to function

the chloroplasts (containing chlorophyll)
... are the structures that allow plants to give off oxygen

So then what receives light from the sun

If a plant cell lacks chloroplasts, it means that it cannot carry out the process of photosynthesis. Photosynthesis is a vital process in which chloroplasts capture sunlight and convert it into energy, while also releasing oxygen as a byproduct.

Therefore, option 1, "give off oxygen," is the correct answer. Without chloroplasts, the plant cell cannot produce oxygen through photosynthesis. The lack of chloroplasts does not necessarily affect the cell's ability to take in food (option 2), give off carbon dioxide (option 3), or take in water (option 4), as these processes are not directly dependent on chloroplasts.

Absolutely! I'll be happy to explain why the correct answer is number 1, not number 2.

To understand this concept, it's important to know the role of chloroplasts in a plant cell. Chloroplasts are organelles responsible for photosynthesis, a process that converts sunlight into energy-rich molecules. In this process, chloroplasts use carbon dioxide and water to produce glucose, a type of sugar.

Now, let's look at the options provided:

1) Give off oxygen: This statement is accurate. During photosynthesis, chloroplasts release oxygen as a byproduct. The oxygen is released into the atmosphere, benefitting not only the plant but also other living organisms that require oxygen to survive.

2) Take in food: This statement is incorrect. Plants use photosynthesis to produce their own food in the form of glucose. They do not rely on consuming external food sources like animals do.

3) Give off carbon dioxide: This statement is incorrect. During photosynthesis, plants actually utilize carbon dioxide as one of the necessary reactants to produce glucose. Therefore, they do not release carbon dioxide but rather absorb it from the atmosphere.

4) Take in water: This statement is generally true for plant cells, regardless of the presence of chloroplasts. Water is vital for various cellular processes, including photosynthesis, nutrient absorption, and maintaining cell turgidity.

In summary, the correct answer is number 1 because a plant cell lacking chloroplasts would not be able to carry out photosynthesis and, therefore, would not release oxygen as a byproduct.
