A chloroplast is an organelle within the cells of plants and certain algae that is the site of photosynthesis, which is the process by which energy from the Sun is converted into chemical energy for growth.

The main role of chloroplasts is to conduct photosynthesis. They also carry out functions like fatty acid and amino acid synthesis.

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.

Function of Chloroplasts They are responsible to carry out photosynthesis, the process of conversion of light energy into sugar and other organic molecules that are used by plants or algae as food. They also produce amino acids and lipid components that are necessary for chloroplast membrane production.

Chloroplast has a structure called chlorophyll which functions by trapping the solar energy and is used for the synthesis of food in all green plants. Produces NADPH and molecular oxygen (O2) by photolysis of water. Produces ATP – Adenosine triphosphate by the process of photosynthesis.

All green parts of a plant contain chloroplasts.

Chloroplasts migrate in response to different light intensities. Under weak light, chloroplasts gather at an illuminated area to maximize light absorption and photosynthesis rates (the accumulation response). In contrast, chloroplasts escape from strong light to avoid photodamage (the avoidance response).

Inside the chloroplasts are stacks of discs called thylakoids. The thylakoid membranes contain chlorophyll and other pigments arranged in antenna arrays to capture light energy for two photosystems called Photosystem I and Photosystem II.

It would not be able to make food because chloroplasts have chlorophyll, which absorbs energy from the sun. This energy is used for photosynthesis. What would happen to a plant if its chloroplasts stopped working? Leaves- they are responsible for making food from the sunlight.

: a plastid that contains chlorophyll and is the site of photosynthesis — see cell illustration.

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. noun.

The chloroplast is the place in a plant cell where photosynthesis happens. Chloroplast is the combination of two biological terms, plastid (an organelle in a plant cell), and chloros, which means green.

A real life example of a chloroplast would be solar panels. Solar panels are used in a variety of products these days, from phone charges, lawn…

The chloroplast is like the solar panels on a house because the solar panels use the sun’s energy to generate power for the house, like the chloroplast does to produce food for the cell.

Chromatin. Chromatin is like a book beacuse it holds the instructions for mitosis and meiosis.

The Nucleus(also known as the Brain) function is to help control eating, movement and reproduction. As of being the brain of the cell, it houses all genetic material (such as your DNA) and/or information. The nucleus is like Barack Obama(the President).

The nucleus is the center core of an atom that has a positive charge and that contains most of the atom’s mass, or the central heart of an organization or group. An example of a nucleus is the center core of an atom.

The nucleus is considered to be one of the most important structures of eukaryotic cells as it serves the function of information storage, retrieval and duplication of genetic information. It is a double membrane-bound organelle that harbours the genetic material in the form of chromatin.

The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell’s genetic material.

Without nucleus the cell will lose its control. It can not carry out cellular reproduction. Also, the cell will not know what to do and there would be no cell division. Gradually, the cell may die.

What is the nucleus?

• The nucleus is an organelle found in most eukaryotic cells, the exception being red blood cells.
• The primary functions of the nucleus are to store the cell’s DNA, maintain its integrity, and facilitate its transcription and replication.

English Language Learners Definition of nucleus biology : the central part of most cells that contains genetic material and is enclosed in a membrane. physics : the central part of an atom that is made up of protons and neutrons. : a central or most important part of something.

The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.

The nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes. It’s the largest organelle inside the cell taking up about a tenth of the entire cell volume.
