Answer:

An organism capable of synthesizing its own food from inorganic substances, using light or chemical energy. Green plants, algae, and certain bacteria are autotrophs.

Explanation:

Here from the above options, Algae is an Autotroph. Autotrophs : An Autotroph is also called as Producer, is an organism that produces complex organic compounds from simple substances present in its surroundings, generally using energy from light or inorganic chemical reactions.

Nutrients- the edible components of food which we intake for maintain life process of living organisms, proper growth, maintenance of their body and nourishment, formation of new tissues,cell and regeneration of dead tissues and cells nutrients.

Nutrition-The procees of taking edible components in our body and it's utilization for maintain life process of living organisms, proper growth, maintenance of their body and nourishment, formation of new tissues,cell and regeneration of dead tissues and cells is called nutrion.

Types of nutrients ✍️✍️✍️

1.Autotrophic

2.Heterotrophic

Autotrophic- The mode of nutrition in which green plants produce their food by the process of photosynthesis is called autotrophic mode of nutrition.

All the green plants are autotrophs. Autotrophs contains the green pigment called chlorophyll which is capable of absorbing and using of Sunlight energy.

Essential process for autotrophic mode of nutrition ---(Photosynthesis)

Photosynthesis- In a series of complex chemical reactions carbon dioxide, which is taken in from the year by the leaf through stomata and water which is absorbed by roots is converted to glucose in the presence of Sunlight and chlorophyll is called photosynthesis. Oxygen and water are released as byproducts.

Oxygen and water are released as byproducts.

The term photosynthesis is coined from two words --- (Photo)-- meaning light and (synthesis) meaning building up.

The process of photosynthesis is complicated oxidation-reduction process resulting in the oxidation of water and reduction of carbon dioxide to form organic compounds like starch.

Photosynthesis is summarised by the equation

Carbon dioxide + Water in the presence of Sunlight with the help of chlorophyll Glucose +Oxygen obtained.

Answer:

autrophic organisms obtain water,carbon dioxide and minerals from their environment and prepare their food which is then used for growth and energy.Autrophic organisms carry out photosynthesis and can prepare their food.They are not independent on other organinsms for their fodd and nutritione.g. photosynthetic plants and some bacteria etc

life cycles of sexually producing organisms involve the alternation of haploid and diploid stages true/false

kolbaska11 [484]

Answer:

True

Explanation:

The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.

Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells.

Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms. During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.

Where is the meristem located?

bezimeni [28]

Answer:

Meristems are classified by their location in the plant as apical (located at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases, especially of certain monocotyledons—e.g., grasses).

Why insect mouth part is important for insect pest control?

Maslowich

Answer:

Insects with rasping/sucking mouthparts actually rasps or scrapes the surface of plant tissue (such as leaves or petals) and sucks up the fluids that ooze from the damaged area of tissue. Examples of pests with rasping-sucking mouthparts include thrips and mites. Thrips prefer to feed on succulent plant tissues.

What is theory of to observe the neucles in cheek cells

solong [7]

Answer: The theory of cheek cells is used for the identification of cheek cells.

Explanation:

The cells of cheek do not have cell wall. They have a cell membrane which allows on certain molecules to pass through it. The nucleus is located centrally in the cheek cells and it stores the DNA. It can be stained with the help of the methylene blue reagent. It appears blue in color which can be observed under the microscope. The cheek cells can be isolated from the buccal cavity by using cotton buds and cotton swabs can help in isolating the cells.
