Why does a plant cell need green chloroplasts and mitochondria?
Explanation: Chloroplasts are present in photosynthetic plants and is responsible for making the food of the plant. It is important to note that plants need both chloroplasts and mitochondria because without one organelle say the mitochondria the entire cell would be unable to carry out its life activities.
Why a plant cell needs green chloroplasts but an animal cell does not?
Human and animal cells do not need chloroplasts because we get our energy from eating and digesting food rather than through photosynthesis. Scientists estimate that there are around 500,000 chloroplasts in a single square millimeter of a leaf. There are actually different colors of chlorophyll.
Do all living plant cells have chloroplasts?
Chloroplasts are important cell structures that give vegetation its distinctive green coloring. They are not present in all plant cells.
Why do plant cells need chloroplast?
Plant Cells, Chloroplasts, and Cell Walls. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
What do plant chloroplasts convert sunlight into?
Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. It is like a solar panel that changes sunlight energy into electric energy. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.
Why do chloroplasts need sunlight?
Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis .
Why are chloroplast so important to plants?
Chloroplasts are also a part of the photosynthesis process. They are organelles that are contained within the plant’s cells. Chloroplast are important for absorbing sunlight and they also play a role with transforming the elements of water and carbon dioxide into food.
Why does chlorophyll make a plant look green?
Chlorophyll is a green pigment that gives most plants their color.The reason that it is green is because it absorbs other colors of light such as red and blue, so in a way the green light is reflected out since the pigment does not absorb it. Plants contain other pigments that reflect different colors, but these are often masked by Chlorophyll.
What is a real life example of a chloroplast?
The definition of a chloroplast is a part of a plant that has chlorophyll and conducts photosynthesis. An example of a chloroplast is a cell in algae that consumes carbon dioxide and releases oxygen while creating sugar. A plastid that contains chlorophyll and is found in the cells of green plants and algae.
