How do these organ systems of a plant work together?

How do these organ systems of a plant work together?

Plant Organ Systems In plants, just as in animals, similar cells working together form a tissue. When different types of tissues work together to perform a unique function, they form an organ; organs working together form organ systems. The root system anchors the plant while absorbing water and minerals from the soil.

What are the main organs of plants and their functions?

In plants, each organ has several jobs, or functions.

• Roots keep a plant in the ground. They also take in water and nutrients from the soil.
• Leaves absorb sunlight, and make food for the plant by photosynthesis.
• The stem supports the leaves and flowers.
• Reproductive organs allow a plant to produce new plants.

What plant organs perform photosynthesis?

The leaves are the primary photosynthetic organs of plants, serving as key sites where energy from light is converted into chemical energy. Similar to the other organs of a plant, a leaf is comprised of three basic tissue systems, including the dermal, vascular, and ground tissue systems.

Why plant organs are different from animal organs?

In plants, just as in animals, similar cells working together form a tissue. When different types of tissues work together to perform a unique function, they form an organ; organs working together form organ systems. Vascular plants have two distinct organ systems: a shoot system and a root system.

Is rhizome part of the shoot system?

Many shoot systems have been modified into organs of food storage, reproduction, or both, called rhizomes, tubers, and corms. The common potato (Solanum tuberosum; Solanaceae) forms such tubers. The much-reduced scale leaves and their associated axillary buds form the eyes of the potato.

Why do you think plant modified their stem?

Stem Modifications Some plant species have modified stems that are especially suited to a particular habitat and environment. A rhizome is a modified stem that grows horizontally underground; it has nodes and internodes. Vertical shoots may arise from the buds on the rhizome of some plants, such as ginger and ferns.

Why are leaves considered organs?

Can a disease affect an organ?

A disease is basically a malfunction. This malfunction may be caused by an external factor like trauma, pathogens, radiation etc. or an internal factor like a heritage of a disease causing gene. Human body is a collection of organs so there is no way that a disease can not affect an organ.

What are the main causes of plant diseases?

CAUSES OF PLANT DISEASES. Plant diseases are caused by both infectious (fungi, bacteria, viruses and. nematodes) and non infectious agents (mineral deficiency, sun burns etc). Infectious plant diseases are caused by living organisms that attack and. obtain their nutrition from the plant they infect.

How do diseases affect the cells of the body?

Some diseases affect the cells, depending on which organ this affects the whole body. Some disease affect the circulation and this affects the organs. Infections have many ways of challenging cells. The immune system may go haywire and attack som cells. There is no endning to this.

What is the impact of farm disease on the environment?

Farmers spend billions of dollars are on disease management, often without adequate technical support, resulting in poor disease control, pollution and harmful results. In addition, plant disease can devastate natural ecosystems, compounding environmental problems caused by habitat loss and poor land management.
