Why do all actively metabolizing cells have mitochondria?

Why do all actively metabolizing cells have mitochondria?

The main function of the mitochondria is to provide energy for cellular activity by the process of aerobic respiration. In this process, glucose is broken down in the cell’s cytoplasm to form pyruvic acid, which is transported into the mitochondrion.

Why do all plant cells contain mitochondria but only some contain chloroplasts?

Plants and animals are very different on the outside as well as on the cellular level. mitochondria, but only plant cells have chloroplasts. ​ Plants don’t get their sugar from eating food, so they need to make sugar from sunlight. This process (photosynthesis) takes place in the chloroplast.

Why do only some plant cells have chloroplasts?

Q 9) Explain why chloroplasts are found only in plant cells? Chloroplasts are found in plant cells only because chloroplasts contain chlorophyll which is essential for photosynthesis. Chlorophyll traps sunlight and uses it to prepare food for plants by the process of photosynthesis.

Why do plant cells have both chloroplasts and mitochondria and not just chloroplasts?

Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light (solar) energy into chemical energy during photosynthesis, while mitochondria, the powerhouse of the cell produces ATP- the energy currency of the cell during respiration.

What is the difference between chloroplast and mitochondria?

Mitochondria are the “powerhouses” of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They’re responsible for capturing light energy to make sugars in photosynthesis.

How does the mitochondria work with the chloroplast?

-Chloroplasts convert the sunlight (absorbed by the chlorophyll) into food, and then mitochondria make/produce energy out of the food in the form of ATP.

Is this statement true or false plant cells have chloroplasts but not mitochondria justify your answer?

False. Explanation: The chloroplast organelles are associated with the process of photosynthesis but the mitochondria are associated with the process of cellular respiration. The plant cells possess both of these organelles that is chloroplast and the mitochondria as the photosynthesis process provides the glucose.

Do plant cells always have chloroplasts?

A chloroplast is an organelle that is only present in plant cells. It is a plastid that contains chlorophyll and is also where photosynthesis takes place.

Do all cells contain mitochondria and chloroplasts?

Both the chloroplast and the mitochondrion are organelles found in the cells of plants, but only mitochondria are found in animal cells. The function of chloroplasts and mitochondria is to generate energy for the cells in which they live. The structure of both organelle types includes an inner and an outer membrane.

What cells contain mitochondria and chloroplasts?

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes. Each of these organelles performs a specific function critical to the cell’s survival.

Why do some plants have more chloroplasts than others?

The majority of chloroplasts are found in the leaves of the plant because these structures have the greatest surface area for absorption. The outer part of a plant stem may also contain chloroplasts.

How are chloroplasts replicated within plant cells?

Replication. The only way these organelles can be replicated is through the same method used by bacteria: binary fission. Like bacteria, mitochondria and chloroplasts grow in size, duplicate their DNA and other structures, and then divide into two identical organelles.

Which plant cell contains chloroplasts?

Chloroplasts are located in the cells of the leaves of green plants and in the cells of eukaryotic algae. They contain a green coloring pigment called chlorophyll that carries out the process of photosynthesis in the presence of sunlight, water vapor and carbon dioxide. 5.0.

What role do chloroplasts play in plant cells?

Chloroplasts are the sites of photosynthesis in eukaryotic cells. They capture sunlight and store the light energy in the form of adenosine triphosphate and nicotinamide adenine dinucleotide phosphate molecules. Chloroplasts play a role in carbon fixation, fatty acid synthesis, amino acid synthesis and the immune response of plants.

Do all plant cells contain mitochondria?

Plant cells do have mitochondria. Mitochondria are capsule-shaped organelles that float freely around the cells and provide it with energy. The energy comes from the nutrients the cell takes in and burns for fuel.

What does the chloroplast do in a plant cell do?

In plant cells, chloroplasts perform photosynthesis, a process that converts light energy from the sun into chemical energy in the form of glucose. Plants can later use this stored chemical energy to carry out activities integral to life, such as growth and reproduction. The process of photosynthesis performed within the chloroplasts uses water, light and carbon dioxide, and it gives off glucose and oxygen.
