Monday: A Day
Aim: How do some plants reproduce?
Do Now: Are fruits different from vegetables? Examine the
fruits and vegetables on the desks, how are they different? Form a definition based on your observations.
Procedure: Discuss do now. Explain how some plants reproduce
sexually and some asecually. Define both and begin to discuss asexual reproduction in plants. Plants reproduce by stems, roots,
and leaves. Tuber=underground root /stem that stores food. carrots, magnolia trees, poplars, rose bushes, apple trees,
sweet potatoes. Plants growby mitosis. Leaves=African violet, begonia, geraniums, placed in soil will grow new plant.
Stems=runners/run along the ground, like strawberries. Potaoes=stem tuber, onion=bulb Both are underground stems. Bulb=short
underground stem that stores food. CUT ONION IN HALF TO SHOW STEM, ROOTS, FOOD. Cutting=small part of plant cut away and planted
to form a new plant. Grafting=joining the stem of one plant to the stem of another plant. Can get trees that will produce
two different kinds of fruit. Done to grow multiple crops from one tree and to protect from disease. COPY: asexual idea
map. Students will also complete the check your understanding questions on page487 of glencoe text. Write Q & A. 1-5
Homework #21: Complete the reteaching idea map for asexual
Tuesday: B Day
Aim: Can we asexually propagate an African violet?
Do Now: Unscramble these scientific terms. itssmoi,
bertus, tticung, frtgangi, lubb, and sxueaal.
Procedure: Students will use cups, soil, and water and will take a cutting of the African violet, plant it and observe of
next few weeks to see if it grows asexually. Complete the study guide worksheet. Introduce sexual reproduction in plants if
Homework #22: Complete Part F on page 331-332
of UPCO Book. Answer questions 1 and 2
Wednesday: A Day
Aim: What is sporulation?
Do Now: Define sporulation using your UPCO book page 330. Lab folders: Lab #5. Bread mold reproduction.
Procedure: Students will view bread
mold that has been grown in class under a stereoscopic
scope. They will also examine some spores from a fern under a microscope. We will discuss how sporulation is related to asexual
reproduction. Identify the parts of bread mold. Stolon, rhizoid, spores , sporangium, and sporangiophore. Complete Lab #5
on page 333 of UPCO book, answer all questions, remove from workbook and place in lab folders.
Homework #23: Finish lab questions if
Thursday: B Day
Aim: Do plants reproduce sexually?
Do Now: Examine plant specimen in classroom.
Procedure: Draw a diagram of a flower and label the parts that will be necessary for sexual reproduction. Reveiw sexual meaning two parents. Sperm
and egg. Use the transparency master to label all the parts and discuss relationship with meiosis. View pollen under microscope.
Discuss self pollination vs. cross pollination. Key words: Sepals=green leaflike part of flower that protects flower while
in a bud. Petals=brightly colored and scented to attract insects for pollination. Stamen=male reproductive organ. Pistil=female
reproductive organ. Ovules=contain the egg cells of a seed plant.
Homework #23: Complete the study guide worksheet.
Friday: A Day
Aim: How does pollination and fertilization occur
Do Now: Copy the following terms into science glossary.
Procedure: . Discuss self pollination vs. cross pollination.
Pollination is the transfer of pollen from the male part to the female part. Birds, insects, wind all play a key role
in pollination. Cross pollination is when pollen from the stamen of one flower is carried to the pistil of another flower.
Self pollination is when the pollen moves from the stamen of one flower to the pistil of the same flower.
Complete the critical thinking worksheet. Halloween treats.
HAVE A GREAT WEEKEND! Be careful. See You Monday!
