Abstract

Describing the process of asexual reproduction: Asexual reproduction is reproduction without sex. In this form of reproduction, a single organism or cell makes a copy of itself. The genes of the original and its copy will be the same, except for rare mutations. They are clones. And as for the product, which is a carrot, it is a biennial herb (Daucus carota of the family Umbelliferae, the carrot family) with a usually orange spindle-shaped edible root.

Process Description

What is asexual reproduction?

• Asexual reproduction is reproduction without sex. In this form of reproduction, a single organism or cell makes a copy of itself. The genes of the original and its copy will be the same, except for rare mutations. They are clones.

What is the function of asxual reproduction?

• Some plants and simple organisms create offspring by making clones, or copies of themselves. Asexual reproduction is practiced by most single-celled organisms including bacteria, archaebacteria, and protists. It is also practiced by some plants, animals, and fungi. organisms that practice asexual reproduction can exchange genetic information to promote diversity using forms of horizontal gene transfer such as bacteria who use plasmids to pass around small bits of DNA. However this method results in fewer unique genotypes than sexual reproduction. Some species of plants, animals, and fungi are capable of both sexual and asexual reproduction, depending on the demands of the environment.

When and where does asexual reproduction take place?

• Asexual reproduction takes place by binary fission, budding (for example, in suctorian ciliates, which produce an internal bud that gives rise to a dispersive larva), or multiple division. This type of reproduction occurs in prokaryotic microorganisms and in some eukaryotic single-celled and multi-celled organisms.

How does asexual reproduction work?

• Unlike sexual reproduction (which combines genes from a female egg cell and a male sperm cell), asexual reproduction produces offspring that are genetically identical to the parent. This can occur in several different ways. Some plants branch out through stems or roots. Bacteria and other prokaryotes split in half in a process called binary fission. Some organisms grow tiny versions of themselves known as buds, while others can regenerate into new individuals from broken parts.

What are the principal steps in asexual reproduction?

• Asexual reproduction results in offspring that are genetically identical to each other and to the parent. All prokaryotes and some eukaryotes reproduce this way. There are several different methods of asexual reproduction. They include binary fission, fragmentation, and budding.

• Binary fission occurs when a parent cell splits into two identical daughter cells of the same size.
• Fragmentation occurs when a parent organism breaks into fragments, or pieces, and each fragment develops into a new organism. For example, a new starfish can develop from a single ray, or arm. Starfish, however, are also capable of sexual reproduction.
• Budding occurs when a parent cell forms a bubble-like bud. The bud stays attached to the parent cell while it grows and develops. When the bud is fully developed, it breaks away from the parent cell and forms a new organism

Object Description

What is the item?

• The item is a carrot. a biennial herb (Daucus carota of the family Umbelliferae, the carrot family) with a usually orange spindle-shaped edible root.

What is the function of a carrot?

• Whether used in countless recipes or eaten raw, the common carrot plant (Daucus carota) offers both a tasty vegetable and bushy foliage for your home garden. Easily grown in U.S. Department of Agriculture plant hardiness zones 4 through 10, these taproots grow into their long, telltale shape if the soil remains friable. This specialized root system has a number of functions for the carrot plant, making it widely successful even through cold weather.

What does a carrot look like?

• Carrots are usually orange in colour, though purple, black, red, white, and yellow cultivars exist. Carrots are a domesticated form of the wild carrot, Daucus carota, native to Europe and southwestern Asia. The plant probably originated in Persia and was originally cultivated for its leaves and seeds.

How does a carrot work or have health benefits?

• Carrots are nutritious. A single carrot, raw or cooked, will provide more than a day’s worth of Vitamin A. Carrots are also a good source of fiber, and deliver a variety of vitamins and minerals in lesser amounts. Low in calories, carrots also carry a low glycemic load (an indicator of how much a serving will raise blood sugar). Carrots contain high levels of several carotenoids, plant compounds that may protect eye and cardiovascular health, and reduce the risk of certain cancers. They also contain other bioactive phytonutrients called polyacetylenes. In carrots, the polyacetylenes falcarinol and falcarindiol have shown anti-tumor activity. They’re versatile in the kitchen, and good to “wash, grab, and go” for snacking. There’s almost no recipe that couldn’t handle a carrot or two.  

What are the principal parts of a carrot?

The main parts of carrots are given below:

The root cap- Conical covering of the tip of the root which covers the apical meristem. It protects against scratches while moving through the soil and excretes a mucus like substance called mucigel that allows the root to move through the soil easily.

Epidermis (skin)- Is the hard outer layer on a root absorbing water from surrounding soil through osmosis.

Root hairs- These are small, microscopic hairs on the outside of the epidermis and serve to increase the surface area of the root. They only survive for only a few days

The Cortex – Is located below the epidermis. Makes up the bulk of the primary root. Main purpose is to store starches. Endodermis- This is the thin layer of cells in the center of the cortex surrounding the xylem and phloem . It forces minerals into the xylem and phloem

Central Core- The Central Core comprised of xylem (a water conducting tissue, transporting water from root to leaf). All Roots contain xylem to conduct water from the soil up the plant and out through the leaves.
