Is onion bulb an organ or tissue?

In botany, a bulb is structurally a short stem with fleshy leaves or leaf bases that function as food storage organs during dormancy. (In gardening, plants with other kinds of storage organ are also called "ornamental bulbous plants" or just "bulbs".)

What level of organization is bulb?

Answer: the level of organization of an onion bulb is ORGAN.

Why is onion bulb an organ?

An onion bulb is only one type of plant storage organ. Many plants store some of the food their leaves make in modified roots, stems, and even leaves. These modified structures are called storage organs.

Is onion bulb a cell?

The clear epidermal cells exist in a single layer and do not contain chloroplasts, because the onion fruiting body (bulb) is used for storing energy, not photosynthesis. Each plant cell has a cell wall, cell membrane, cytoplasm, nucleus, and a large vacuole. ... Firm, small onions are best for microscopy.

Do onion cells have mitochondria?

To answer your question, onion cells (you usually use epithelial cells for this experiment) are 'normal' cells with all of the 'normal' organelles: nucleus, cytoplasm, cell wall and membrane, mitochondria, ribosomes, rough and smooth endoplasmic reticulum, centrioles, Golgi body and vacuoles.

What is the level of Organisation of blood?

For example, the heart and the blood vessels of the cardiovascular system circulate blood and transport oxygen and nutrients to all the body cells. Levels of Organization: Molecules form cells. Cells form tissues, and tissues form organs. Organs that fulfill related functions are called organ systems.

What level of organization is red blood cells?

EXAMPLES. Using the circulatory system as an example, a cell in this system is a red blood cell, the heart's cardiac muscle is a tissue, an organ is the heart itself, and the organ system is the circulatory system. An organism is made up of four levels of organization: cells, tissues, organs, and organ systems.

What is the level of Organisation of euglena?

Option C – cell

Examples are Amoeba, Euglena Life can be organized into several different levels of function and complexity. These functional levels are: cells, tissues, organs, systems and organisms.

What is the characteristics exhibited by all living organisms?

Properties of Life. All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

What is onion bulb?

The bulbs are composed of shortened, compressed, underground stems surrounded by fleshy modified scale (leaves) that envelop a central bud at the tip of the stem. In the autumn (or in spring, in the case of overwintering onions), the foliage dies down and the outer layers of the bulb become more dry and brittle.

What is onion bulb in biology?

1. ( Botany) a rounded organ of vegetative reproduction in plants such as the tulip and onion: a flattened stem bearing a central shoot surrounded by fleshy nutritive inner leaves and thin brown outer leaves. Compare corm. 2. ( Botany) a plant, such as a hyacinth or daffodil, that grows from a bulb.

What type of storage organ is an onion?

Examples of storage organs include: Bulbs – Modified leaf bases (found as underground vertical shoots) that contain layers called scales (e.g. onions) Storage Roots – Modified roots that store water or food in an enlarged central stele (e.g. carrots)

What type of cell is the onion cell?

They are the prokaryotic cells. They do not have organelles bounded with membrane as they do not have a complex body. They even lack membrane around the nucleus. Onion cell is a eukaryotic cell with well-defined membranes around the organelles.

What does an onion cell contain?

An onion is a multicellular (consisting of many cells) plant organism.As in all plant cells, the cell of an onion peel consists of a cell wall, cell membrane, cytoplasm, nucleus and a large vacuole. The nucleus is present at the periphery of the cytoplasm. The vacuole is prominent and present at the centre of the cell.

Is onion an organism?

Since the onion (Allium cepa) is a diploid organism having a haploid genome size of 15.9 Gb, it has 4.9x as much DNA as does a human genome (3.2 Gb). Other species in the genus Allium vary hugely in DNA content without changing their ploidy.
