Which is an organelle that performs photosynthesis and is paired with its correct function?
A) Chloroplast-converts light energy into chemical energy.
B) Chloroplast-converts chemical energy into light energy.
C) Mitochondrion-converts cellular energy into glucose chemical energy.
D) Mitochondrion-converts energy found in glucose into energy for cells.
Answer:
A
Explanation:
Plants absorb the light and turn it into chemical energy with the help of chloroplasts
Chloroplast is the organelle in the plant cell which converts light energy into chemical energy. Chloroplast performs photosynthesis. Thus, the correct option is A.
What is Chloroplast?A chloroplast is a type of membrane-bound organelle which is known as a plastid which conducts photosynthesis mostly in the plant cells and algal cells. Chloroplast are the organelles which convert the light energy into chemical energy in the form of carbohydrates (sugar). The photosynthetic pigment chlorophyll is present in the chloroplast which captures the energy from sunlight, converts it, and stores it in the energy-storage molecules such as ATP and NADPH while freeing up the oxygen molecule from water in the cells.
Chloroplast is the double membranous organelle which is present in the plant cells and certain algal cells. This organelle is absent in the animal cells. Thus, they cannot perform photosynthesis.
Therefore, the correct option is A.

Answer:
Structure that organizes motion of chromosomes. Cytoplasm. Material in cell; contains chemical wealth: sugars, amino acids, and proteins a cell uses to carry out everyday activites. Vacuole. Saclike structure (large in animal cell); stores water, salts, carbs, and proteins. Plays a role in disposing waste.
Explanation:
There are various structures that are found present in a cell. And these structures have peculiar functions they carry out in the cell. Chromosomes are found in the nucleus of a cell. During cell division there is the needed movement of the chromosomes.
The structure that organizes motion of the chromosomes is the centriole
The centriole is a structure found in the animal cells near the nucleus that aid in the movement of chromosomes through the action of the microtubule and spindle fibres. They help to assemble these microtubules and spindle fibres to aid movement of chromosomes.Learn more: https://brainly.com/question/24552946

What are bones?Bone is a solid bodily tissue made up of cells encased in a lot of dense intercellular substance. Collagen plus calcium phosphate, the two main components of this substance, set bone apart from other hard tissues like chitin, enamel, or shell. The individual bones that constitute the human spine or the skeletons of many other vertebrates are composed of bone tissue.
The mechanical stress of soft tissues, like the muscles contracting as well as the expansion the lungs, requires structural support from bone. Bone also protects soft tissues and organs, like the blood-forming system, and serves as a protective place for specialized tissues.

What are the characteristics of the hot and dry deserts?Hot and dry deserts have extremely hot climates and challenging environments. There is very little biodiversity in hot deserts because of the harsh climate. Few species are specialized enough to survive there. Apart from this, the climate is very dry with less than 250 mm of rainfall a year.
According to the context of this question, cold deserts have extremely low temperatures and snowfall. While coastal deserts occur in cool to warm areas along the coast. They have cool winters and long, warm summers. Coastal deserts are located on the west coasts of continents between 20° to 30° latitude.

Explanation:
Carbohydrates are composed of the carbon, hydrogen, oxygen in the ration of 1:2:1 which means hydrogen atoms are double than oxygen and carbon atoms. Carbohydrates are also known as sugars or polymer of sugars.
Lipids are composed of long chains of fatty acids made up of carbon, hydrogen, and oxygen molecules that are insoluble however ade up of organic molecules.
DNA or deoxyribose nucleic acid is the basic unit of cell and known as genetic material. It is made up of ribose sugar, a nitrogenous base, and phosphate backbone so elements that make these nutrients are Carbon, hydrogen, and oxygen with nitrogen and phosphorus.
Proteins are made up of amino acids that have carbon, hydrogen, oxygen, and nitrogen element in them.
The 4 macromolecules are namely Carbohydrates, Proteins, Nucleic acids, and Lipids. The composition of each macromolecule is defined by the elements present.
The symbols for the element that makes up each macromolecule are listed below:
