17 Questions
Plants can reproduce either sexually or ______
asexually
Tubers are plant parts that are enlarged to form storage containers that the plants use to hold ______ that allow them to feed their offspring
nutrients
One strategy of plants reproducing asexually is through vegetative reproduction, a type of reproduction in plants from its vegetative parts or specialized reproductive ______
structures
Corm plants are vertical, fleshy, underground stem that acts as a food-storage structure in certain seed ______
plants
Sexual reproduction occurs in the sexual organ of the ______
flower
______ PLANTS are a horizontal underground plant stem capable of producing the shoot and root systems of a new plant.
RHIZOMES
Another method used for plants to grow is by means of artificial plant propagation with a little help from the human. It is very useful because plants can grow faster than plants grown from the seeds. Male Organs of a Flower A. Stamen – male reproductive part of the flower.
ASEXUAL
Woody plants are reproduced through grafting, which attaches a piece of stem from one plant to the root or rootbearing of another plant. The result of combining it to a rootbearing stem host is called stock, and the grafted stem part is called the scion.
GRAFTING
Flowering plants may develop and reproduce through pollination wherein the pollen is transferred from the anther to the stigma. This will happen with the help of insects, animals, and wind. Double fertilization process is seen in plants that bear fruits which may contain one or many seeds.
POLLINATION
Reproduction is part of a life cycle in which individuals grow, develop, and reproduce according to instruction encoded in DNA. The resulting offspring are identical to the parent in terms of characteristics. Asexual reproduction is also called as clonal reproduction.
REPRODUCTION
Which of the following is a method of asexual reproduction in plants?
Fission
What is the function of the ovary in a flower?
Contains ovules
Which of the following is a method of asexual reproduction in animals?
Budding
What is the function of the filament in a flower?
Holds up the anther
What is the process where the body breaks into two or more parts, with each fragment capable of becoming a complete individual?
Fragmentation
What is the function of tubers in plants?
To store nutrients for feeding the offspring
What happens in the sexual organ of a flower during sexual reproduction?
Double fertilization process
Study Notes
Plant Reproduction
- Plants can reproduce either sexually or asexually.
- Tubers are plant parts that store nutrients and water, allowing plants to feed their offspring.
Asexual Reproduction
- Vegetative reproduction is a type of asexual reproduction in plants, where new plants grow from vegetative parts or specialized reproductive structures.
- Corm plants are vertical, fleshy, underground stems that act as food-storage structures in certain seed plants.
- Rhizomes are horizontal underground plant stems capable of producing the shoot and root systems of a new plant.
Sexual Reproduction
- Sexual reproduction occurs in the sexual organ of the flower.
- Male reproductive part of the flower is the stamen, which consists of the anther and filament.
- Pollination is the process of transferring pollen from the anther to the stigma, allowing for fertilization.
- Double fertilization occurs in plants that bear fruits, which may contain one or many seeds.
Artificial Plant Propagation
- Artificial plant propagation is a method of plant reproduction that involves human assistance, resulting in faster growth than seeds.
- Grafting is a method of reproducing woody plants, where a piece of stem from one plant is attached to the root or root-bearing part of another plant.
- The resulting plant is called the stock, and the grafted stem part is called the scion.
Key Functions
- The ovary in a flower is the female reproductive part, where fertilization occurs.
- The filament in a flower is the stalk that supports the anther.
- Tubers in plants store nutrients and water, allowing plants to feed their offspring.
Additional Terms
- Fragmentation is the process where the body breaks into two or more parts, with each fragment capable of becoming a complete individual.
- Clonal reproduction is another term for asexual reproduction, where the resulting offspring are identical to the parent in terms of characteristics.
This quiz reviews the processes of reproduction and development in plants, focusing on vegetative reproduction through modified stems like runners, tubers, corms, and rhizomes. It also covers the essential characteristic of reproduction in organisms and the distinction between sexual and asexual reproduction.
