Asexual reproduction in Plants

Today we continued learning about asexual reproduction but specifically within the Plant kingdom.

Unlike many animals plants continue to grow throughout a lifetime. This is aachieved by the roots and stems of plants which contain an area where growth occurs called meristems.
In the meristem, unspecialized cells undergo miotic division repeatedly, creating new cells.

After a certain period of time these meristem cells ( general cells) become specialized to form into root, or stem, or even leaf cells. Then at this point those specialized cells do not undergo anymore divisions.

Because of these meristem celss, plants can be tricked into reproducing easily.
A unique plant or tree can be cut and hundreds of identical offspring can be grown from just one plant. There are multiple ways for plants to reproduce asexually. Cuttings, Layering, runners, grafting, roots, and tissue cultire.

For a greater understanding of these reproduction methods please refer to pg 36 -40 in your course textbook.

HOMEWORK
Review today's overhead notes, read pg 36 -40
Answer # 1- 5 on pg 40
Review all of chapter 1 for Monday's Test

Tomorrow is a microview lab day and it must be complete by the end of the period.
Please read it in advance. It is in the course kit.

Asexual Reproduction in Animals

Today we reviewed the concept of mitotic division. We understood that all living cells must reproduce to ensure the survival of their species or their multicellular being.

There are many other ways in which cells and organism use to ensure the continuaity of
themselves and their species.

Today we have looked various reproductive stages in the 5 general kingdoms of the planet.
(We have exluded plants today as we will discuss those in greater detail tomorrow in class.)

Today we have specifically looked at:
Bacteria ( binarry fission)
Monera ( mitosis)
Fungi (fragmentation, spores, budding)
Animalia invertabrates - sponges, jellyfish, insects, (regeneration)

We have looked at regeneration, fragmentation, budding, binary fission all in which reproduce an identical offspring. However wehn Environmental conditions change for these unique organisms, they have the ability to also share genetic information through a process called conjugation.

To learn further please read in your textbooks pg 29 -35.

HOME WORK:

Complete handouts given in class ( double sided)
Review chart copied in class.
Answer questions # 1 - 6 on pg 35 in textbook.

CELLS GROWI, AGE, DIE..

Today in class we discussed the truth that all cells live and then eventually they die. For an organism to sustain health and vitality it must regenerate new cells to replace the old, damaged and worn out cells.

We looked at many different cells. Skin cells, blood cells, brain cells, even stomach cells. Each have their own unique responsibilities to the organism and some of the last for years like brain tissue, some only day such as stomach cells.

We discussed the issues of how cancer develops and what factors can lead to it.
Tomorrow in class we will cover indepth the topic of cancer, some text questions and sorts.

MITOSIS MICROSLIDE VIEWER LAB DAY 1

In the past 2 days we have studied and learned the stages of cell development and growth.
The process in which cells divide and make new living cells is called Mitosis.
Mitosis has 5 distinct phases.

Interphase, Prophase, Metaphase, Anaphase, Teleophase.

The next step to follow would be cell division a seperate process to complete the formation of two cells.

**IPMAT** each of these stages has unique and important role and function in creating an identical copy of the pre-existing cell. (a daughter cell)

Today's class as well as tomorrow you will be using premade slides to view the different stages of mitosis in a plant. Remember there are difference between plant and animal cells and their organelles, so becareful when labelling them appropriatley.

Use your notes from the course kit, text and microslide booklets to fill in the blanks of the lab.

This lab will take us two days to complete as you will have to draw and label the cells that you view in the circle (field of view) in your lab booklets.

Here is a web site that will help make them more clear to see in real living cells

ANIMAL and PLANT cells.

SECRETS OF THE CELL VIDEO: 30 minutes, general idea and concepts on how unique and important cells are. Key concepts were:

Prokaryotic are primative cells, and lack a true nucleus. Examples are bacteria.
Eukaryotic cells are larger and contain organelles such as a nucleus, mitochondrion, chlooplast, ribosomes, etc.
Cells play an integral part of the life cycle. Even from the most pimative species and organism to the complex organism they are conected and rely on eachother indirectly for survival.

LESSON MATERIALS:
Today you were given 2 colouring diagrams which are to be completed for studying purposes for MONDAY's QUIZ!

Using your textbook and handouts fil in the blank diagrams of the plant and animal cell in the course kits.

Please read in your course kits pg 2- 6.
Please complete the charts in your course kits by filling in both the structure and function of each particular organelle.

*** Note not all organelles will be found in our primative textbooks so please use the internet or our own blog site archives on this site to get information on cell organelles to help fill in the blanks on your course kits.
