This document discusses and compares asexual and sexual reproduction. It defines reproduction as the process by which living organisms form new individuals of the same kind. The two main types of reproduction are then explained as asexual reproduction, where offspring are genetically identical to the parent, and sexual reproduction, which involves the fusion of egg and sperm cells. Examples of asexual reproduction methods like binary fission, budding, fragmentation, and spore formation are provided. For sexual reproduction, the document describes both internal and external fertilization and the sexual reproduction process in plants specifically. Learning tasks at the end instruct students to answer questions about the material on Edmodo.

A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC
How Do Organisms Reproduce ? - Class 10 CBSE science (BIo)Amit Choube
Reproduction is an integral feature of all living beings. The process by which a living being produces its own like is called reproduction.
Importance of Reproduction:
Reproduction is important for each species, because this is the only way for a living being to continue its lineage. Apart from being important for a particular individual, reproduction is also important for the whole ecosystem. Reproduction helps in maintaining a proper balance among various biotic constituents of the ecosystem. Moreover, reproduction also facilitates evolution because variations come through reproduction; over several generations.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

3. Identify the difference between Asexual and Sexual
reproduction.
Differentiate the different types of asexual and sexual
reproduction of an organism.

different organism works.
OBJECTIVES
4. INSTRUCTION:
Watch a short video presentation about the topic.
Take down notes of the important points from the video so
you can participate the class discussion and activity.
Make sure to answer your teacher’s questions for the
additional points.
LET’S START
5. 1. What is reproduction?
2. What are the two types of reproduction?
3. Give examples of asexual reproduction.
4. Give examples of sexual reproduction.
GUIDE QUESTIONS
6. What is
REPRODUCTION?
It is the process by which
living organisms like humans,
animals, plants, and other
organisms form new
individuals of the same kind.
7. What are the 2 types
of REPRODUCTION?
Asexual Reproduction
Sexual Reproduction
Is the process by which a single
organism produces genetically
identical offspring.
Is the formation of offspring from
the fusion of gametes (egg & sperm
cell) called Fertilization.
9. Fission: Asexual
Reproduction
It occurs in prokaryotic
microorganisms and in some
invertebrate, and multi-celled
organisms.
After the DNA molecule replicates, an
organism splits into two separate
organisms.
Organisms like the amoeba, bacteria,
euglena, etc., exhibit binary fission.
10. Budding: Asexual
Reproduction
Budding occurs when a new organism
starts growing from the parent’s body.
This bud later develops into a mature
organism. It may stay attached to the
parent’s body or break off.
Some examples are hydra, yeast, and
corals.
11. Fragmentation:
Asexual Reproduction
Fragmentation is when the body of an organism
breaks into several parts.
Fragmentation is also known as splitting.
Each fragment will develop into a mature clone
genetically and morphologically identical to its
parent.
The organisms that will reproduce through this
process have a specific organs or zones to break
off easily.
Some examples are the planaria, starfish, and
hydra.
12.
13. Parthenogenesis:
Asexual
Reproduction
Parthenogenesis is a natural form of asexual reproduction in
which growth and development of embryos occur without
fertilization by sperm.
In animals, parthenogenesis means development of an embryo
from an unfertilized egg cell.
14. Spore Formation:
Asexual
Reproduction
Spores are formed by fungi
and are often contained
within a structure known as
a sporangium which
disintegrate releasing the
spores into the
environment,
15. Vegetative Reproduction:
Asexual Reproduction
Vegetative reproduction is a form of asexual
reproduction found in plants where new
independent individuals are formed without the
production of seeds or spores.
17. What are the 2 types of SEXUAL
REPRODUCTION?
Internal Fertilization
External Fertilization
18. SEXUAL REPRODUCTION IN PLANTS
The vegetative part of a
flower consists of the
following:
Petals: This is a bright-
coloured part that attracts
bees, insects, and birds.
Sepals: Sepal is the green-
coloured part beneath the
petals to protect rising
buds.
19. Stamen: This is the male reproductive organ. It consists of two parts
namely: anther and filaments.
The anther is a yellowish, sac-like structure, involved in producing
and storing the pollens.
The filament is a slender, threadlike object, which functions by
supporting the anther.
Pistil: This is the innermost part and the female reproductive organ
of a flower which comprises three parts -stigma, style and ovary. This
is collectively known as the pistil.
Stigma: It is the topmost part or receptive tip of carpels in the
gynoecium of a flower.
Style: It is the long tube-like slender stalk that connects stigma
and the ovary.
Ovary: It is the ductless reproductive gland that holds a lot of
ovules. It is the part of the plant where the seed formation takes
place.
