What is the internal structure of a leaf?
The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis. The central leaf, or mesophyll, consists of soft-walled, unspecialized cells of the type known as parenchyma.
How do plants reproduce?
Every part of a plant has a specific job to help it either grow, survive, or reproduce. Roots grow outward from the seed and hold the plant in place while soaking up water and nutrients from the soil. Leaves make food for the plant from the sun and carbon dioxide in a process called photosynthesis. Reproduction is helped by pollination, where animals fertilize flowers while eating or moving around on the pollen.
What does the spine do to a plant?
Your spine helps your body stand up straight. This is part of what a stem does; a stem provides support for the plant. Stems also move water and food from the roots throughout the plant, like your veins move blood throughout your body. Or, like plumbing pipes move water through a house.

What organelle is responsible for photosynthesis?
Chloroplast. These organelles are interesting in that they are only found in plant cells. They contain chlorophyll, giving the foliage of the plants their green color and aiding in the process of photosynthesis. The function of the chloroplast is to capture sunlight to conduct photosynthesis.
Why do succulent leaves hold water?
These swollen leaves hold onto water so that in the case of drought, the plant has enough water reserves to survive.
What is the control room of a plant cell?
The nucleus is the control room of the plant cell and is the most important part of any plant cell. It takes on a spherical shape and contains the DNA of the plant within its chromosomes, holding on to all of the plant’s genetic hereditary information. It is responsible for coordinating all of the metabolic functions, including cell growth, protein synthesis, and cell division. By taking care of this, the nucleus regulates all of the functions of the cell. Contained within the nucleus are also other organelles, some of which produce ribosomal RNA.

Where is the root of a plant located?
The root is located below the ground. It helps to anchor the plant to the ground so it does not fall over. It absorbs water and nutrients from the soil and sends it to the stem.
What are the two parts of a plant?
The parts of the plant body are also differentiated into two kinds of functional plant organs: vegetative and reproductive. The vegetative structures include the root, stem, and leaves; the reproductive parts consist of the flower, fruit, and seed.
What are the two main parts of the plant body?
The parts of the plant body of the angiosperms are divided into two distinct systems: the root and shoot. In terrestrial plants, the root system is the plant organ that is normally underground (descending) while the shoot system is above ground (ascending). The root system consists of the primary root and its branches, or a mass of fibrous roots. The plant shoot system consists of the stem, leaves, and reproductive organs.
Which part of the plant absorbs water and nutrients?
In general, it is the root that provides anchorage and absorbs water and nutrient elements which are transported to the leaves via the stem (trunk, branches, and twigs). At the same time, the leaves absorb carbon dioxide from the air which is utilized in the production of carbohydrate through the process of photosynthesis. This carbohydrate is in turn transported, again via the stem, to the different parts of the plant, including the roots and the reproductive structures. At certain periods of organ development, the stored photosynthate may again be retransported to other plant organs.
How can knowing the different parts of plants help in crop production?

What is the area of the stem where leaves grow from?
The area of the stem where leaves grow from is called a node. The stalk of the leaf that connects to the node is called the petiole. The area of the stem between nodes is called the internode. We also explored the vascular system of a plant stem. The vascular system includes the phloem and the xylem.
What is the phloem in a tree?
The phloem is a network of tubes in the stem that transport food to the rest of the plant. Have you ever witnessed sap oozing from a tree? You are actually witnessing sticky phloem contents leaking out. When you eat syrup, you are eating the sugary contents transported in the phloem. A way to remember the phloem transports food throughout the plant is to think of the beginning sound of phloem, which sounds like the f in food.
How do leaves transport food to the rest of the plant?
Everyone knows plants manufacture food from the sun, but how do leaves transport food to the rest of the plant? This movement of food and water is performed by the vascular system. The vascular system is comprised of two main tissues, the phloem and xylem.

What are the cells that make up a plant's growing points called?
Specialized groups of cells called meristems are a plant's growing points. Meristems are the site of rapid, almost continuous cell division. These cells either continue to divide or begin to differentiate into other tissues and organs. How they divide, and whether they ultimately become a tissue or an organ, are controlled by a complex array of internal plant hormones but also can be influenced by environmental conditions. In many cases, you can manipulate meristems to make a plant do something you want, such as change its growth pattern, flower, alter its branching habit, or produce vegetative growth.
What are the basic structures of plants?
Cells are the basic structural and physiological units of plants. Most plant reactions (cell division, photosynthesis , respiration, etc.) occur at the cellular level. Plant tissues ( meristems , xylem , phloem, etc.) are large, organized groups of similar cells that work together to perform a specific function.
What is the unique feature of plant cells?
A unique feature of plant cells is that they are readily totipotent. In other words, almost all plant cells retain all of the genetic information (encoded in DNA) necessary to develop into a complete plant. This characteristic is the main reason that vegetative (asexual) reproduction works.
