What is the leaf structure of corn?
The leaf blades are 10-40″ long and ¾–4½” across; they are ascending toward their bases, but arching toward their tips, and rather floppy overall. The leaf blades are linear to linear-lanceolate in shape, while their margins are entire (without conspicuous teeth) and often ciliate near the bases of the leaf blades.
What are 4 parts of a corn plant?
Ear or Cob: The core on which the kernals grow, protected by a husk of tightly wrapped leaves. Kernels: The plant’s seed and the part you eat. Stalk: The stem of a corn plant. Roots: The part that goes deep into the soil and carries food and water to the corn plant.
What are the parts of corn plant?
Regardless of the variety, corn plants have the same basic parts and plant structure.
- Tassel. The tassel is the male portion of the flower.
- Stalk. Corn stalks are the main body of the plant.
- Leaves. Like any plant, corn plants can have numerous leaves on the stalk.
- Silk.
- Husk.
- Ear.
- Roots.
What is corns structure?
The corn seed (kernel) is composed of four main parts: the endosperm, the pericarp, the germ, and the tip cap. The endosperm is most of the dry weight of the kernel. It is also the source of energy for the seed. The pericarp is the hard, outer coat that protects the kernel both before and after planting.
Is corn a root stem or leaf?
Corn grows on a single stem called a stalk. Stalks can grow up to ten feet tall. The plant’s leaves emerge from the stalk. A single corn stalk can hold between 16 and 22 leaves.
What is leaf arrangement?
Leaf Arrangement The arrangement of leaves on a stem is known as phyllotaxy. The number and placement of a plant’s leaves will vary depending on the species, with each species exhibiting a characteristic leaf arrangement. Leaves are classified as either alternate, spiral, opposite, or whorled.
What is the top part of a corn plant called?
the tassel
At the top of a mature corn plant is the tassel, the male part of the plant. Along the stalk are the leaves and the ears of corn, wrapped closely in husks. Hundreds of filaments, called silk, protrude from the top of each ear.
What are the three parts of a corn kernel?
Three important parts of the corn kernel are the pericarp (seed coat), endosperm, and embryo.
What type of stem is corn?
Is corn a flower or stem?
A Little about Corn Like other members of the grass family, corn is a monocot. It has only one cotyledon or seed leaf. Corn plants contain both male and female flowers in different locations on the plant. An ear of corn is actually a female flower stalk, resting between the sheaths of the leaf and stem.
What is the tassel on a corn plant?
The tassel represents the male flower on a corn plant, while the ear shoots represent the female flowers. Interestingly, both reproductive structures initiate as perfect (bisexual) flowers, containing both male and female reproductive structures.
What is the outer part of corn called?
The pericarp is the outer covering that protects the kernel and preserves the nutrient value inside. It resists water and water vapor-and is undesirable to insects and microorganisms. The germ is the only living part of the corn kernel.
Is corn a stem leaf root or flower?
Roots: Carrots, Potatoes and Onions. Flowers: Broccoli, Cauliflower Cabbage. Nuts and Seeds: Maize (corn), Beans, Rice, Pistachios and Cashews. Leaves: Lettuce, Spinach and Bok choy.
Is corn a seed or stem?
“Corn is a seed derived from the flower/ovary of the corn plant,” he says, “so is technically a fruit.” More specifically, corn is a caryopsis, which is a type of fruit in which the seed coat is tightly fused with the pericarp (that’s the fleshy bit, like the part of a peach that you eat).
What does corn tassels look like?
The male flower of the corn plant is known as a corn tassel. After the bulk of the plant growth is complete, tassels will appear on top of the plant. Corn plant tassels can be green, purple, or yellow. The tassel’s job is to produce pollen that encourages the growth and ripening of the corn ear.
What part of the leaf wraps around the stem of corn?
The part of the leaf that wraps around the stem is called the node. The tassel and the corn ears are responsible for reproduction and formation of the corn kernels. The tassel is the “male” part of the plant, which emerges from the top of the plant after all of the leaves have developed.
What is the structure and function of corn?
Corn Plant Structures and Functions Tassel:the male part of the corn plant that contains the pollen. The tassel is on top of the corn plant. Leaf:a full grown corn plant has 16-19 leaves although 5 leaves fall off by the time the plant tassels. The leaf provides the surface area where light is intercepted and photosynthesis takes place.
What is the male part of the corn plant?
Tassel: the male part of the corn plant that contains the pollen. The tassel is on top of the corn plant. Leaf: a full grown corn plant has 16-19 leaves although 5 leaves fall off by the time the plant tassels. The leaf provides the surface area where light is intercepted and photosynthesis takes place.
How do you identify droopy leaves on a damaged corn plant?
Identifying true “droopy” leaves on shredded, hail-damaged corn plants can be quite difficult, whereas leaf collars are often still identifiable. Thus, you can usually stage a damaged crop by the leaf collar method and then add one or two more leaves to the count in order to use the defoliation chart. See my Corny News article for more details.
