Which of the follow correctly describe the function of a seed?   Question 31 options:   Contains the plant embryo and a tissue such as endosperm to provide nutrition for early plant growth.   Grows from the ovary of a flowering plants and surrounds the seed.  Provide protection and/or attracts animals to aid in seed dispersal.   The reproductive structure of the angiosperms.     The reproductive structure of the gymnosperms.     Carries the microgametophyte and sperm cells during sexual reproduction in angiosperms.

A botanist discovers a new species of plant in a tropical rain forest. After observing its anatomy and life cycle, he notes the following characteristics: 1. Sperm contained in pollen grains, 2. Sporophyte dominant, 3. Seeds contained in fruits. 4. Xylem with tracheids, Mosses Green Algae Ferns Pines/gymnosperms Flowering plants/angiosperms

Examine an image of longitudinal section the rough a Coleus stem tip. Can you find a node where procambium diverges in to the leaf primordium?

10) A team of botanists discovers a new species of plant in a tropical rain forest. After observing its anatomy and life cycle, they note the following characteristics and observations:- Presence of pollen cones and ovulate cones- Diploid-dominant- Seeds- vascular tissues- Absence of anything that resembles a flowerThis plant is probably a(n)   Group of answer choices moss angiosperm protist gymnosperm fern

Part B: The Embryo Sac Examine the demonstration slide of a c.s. of a lily ovary. Find an ovule. Identify the funiculus, the chalaza, the integuments, the micropyle, and the developing female gametophyte. The latter is commonly referred to as the embryo sac in angiosperms. If your slide has several embryo sacs, they are likely to be at variable stages of development. (See text Figure 19-18b,c, page 469.) Like the female gametophyte in pine, the embryo sac develops from a megaspore. 5. Label the ovary wall, ovule, integuments, and developing embryo sac in Figures 3. and 4. below. Figure 3.

Which of the follow correctly describe the function of a flower?   Question 29 options:   The reproductive structure of the angiosperms.     Contains the plant embryo and a tissue such as endosperm to provide nutrition for early plant growth.   Grows from the ovary of a flowering plants and surrounds the seed.  Provides protection and/or attracts animals to aid in seed dispersal.   Carries the microgametophyte and sperm cells during sexual reproduction in angiosperms.   The reproductive structure of the gymnosperms.

The classification of the seed plants has varied. If a person groups all seed plants together in one large Division Spermatophyta, then they have two classes—the class                 with naked seeds and the class                   , plants with carpels. On the other hand, many people (and this book) use four divisions, not one. List the three divisions of “gymnosperms” and the one division of flowering plants.

Which of the follow correctly describe the function of a cone?   Question 32 options:   Carries the microgametophyte and sperm cells during sexual reproduction in angiosperms.   Contains the plant embryo and a tissue such as endosperm to provide nutrition for early plant growth.   The reproductive structure of the gymnosperms.     Grows from the ovary of a flowering plants and surrounds the seed.  Provides protection and/or attracts animals to aid in seed dispersal.   The reproductive structure of the angiosperms.

What is (are) the function(s) of fruit? 2. From what structure (s) do fruits develop? 3. Give an example of a fruit that is dry at maturity, that people generally eat while it is still immature (fleshy). Name 4. Give an example of a fleshy fruit that is partially derived from the receptacle? 5. In most fruits, the ovary wall develops into what 3 layers? 139 141

Which of the following is NOT a gymnosperm? O lily gingko U cycad gnetophyte

Seed cones of conifers are more complex than pollen cones. Seed cones are                    cones, each consisting of a shoot with axillary buds. The main axis of the cone bears leaves called                , rather than sporophylls, and each of these has an axillary bud that bears the                 . The axillary bud is microscopic, and its                 are fused laterally, forming an                  scale.

Which of the following traits are unique to Angiosperms? Heterosporous Pollen tube growth Dominant sporophyte Triploid tissue present in the seeds
