To review:
The effect of bees on the fruit mass and seed formation.
Introduction:
Pollination is the transfer of pollen grains from the anther (male part) of a flower to the stigma (female part) of a flower. Pollination occurs within the same plant (self-pollination) and where the female and male parts are present on the separate flowers or plants (cross- pollination). The pollination is a necessary process for the plants in order to reproduce and produce seeds. Most of the plants depend on bees or insects for it. These are pollinators that collect the pollen and nectar from the flowering plant. In the given experiment, the seeds of gooseberry plant were self-pollinated, cross-pollinated by hand, and cross-pollinated by bees. The results of the experiment are given in the graph below:

- The three main parts of a typical mature eudicot seed are the _______ . a. pollen grain, egg, and seed coat b. embryo, endosperm, and seed coat c. megaspores, microspores, and ovule d. embryo, cotyledons, and seed coatarrow_forwardLook at the flower, observe color, size of petals and height of stamen and pistil. What type of pollination does it present? - Self pollination - wind cross pollination - bird cross politicizationarrow_forwardWhat are the relationship of angiosperms and gymnosperms with pollinator species,? please cite at least 5 pollinators species (definition, example, and how they pollinate).arrow_forward
- Many flowers have both anthers and pistils. What prevents self-pollination and later self-fertilization?arrow_forwardCompare wind-pollinated and animal pollinated seed vascular plants in terms of the following characteristics: -Pollination method -Relative efficiency of pollination method -Plant types -Reproductive organs -Adaptations that promote pollination. Tabulate your answersarrow_forwardWhich of the following statements is false?a. Auxin and gibberellin promote stem elongation.b. Cytokinin triggers growth of lateral buds.c. Abscisic acid promotes water loss and dormancy.d. Ethylene promotes fruit ripening and abscissionarrow_forward
- Imagine that you are a member of a research group conducting research on fruit type and seed dispersal. Your group has submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document.Question: Why is seed dispersal important in the life of plants? What would be the consequences of having seeds that simply fell to the ground underneath the parent tree?arrow_forwardSuppose that 100 pollen grains land on a stigma, and 50 mature seeds are formed in the fruit. What does this indicate about the pollination process and success? A) 100% success: 100 pollen grains grew to 50 ovules, two to each, and double fertilization occurred. B) 100% success: Only 50% of the pollen grains germinated, but each produced 2 sperms to complete double fertilization in 50 seeds. C) 50% success: 50 sperm fertilized 50 eggs, and 50 sperm fused with 50 polar nuclei. D) 50% success: 50 sperm fertilized 50 eggs, and 50 sperm fused with 100 polar nuclei. correct answer and explanation why please.arrow_forwardWhich of the following sequence represents the events that take place in the development of a fruit? -pollination, fertilization, germination of pollen tubes, ovule matures, embryo forms. -pollination, double fertilization, ovule matures, embryo forms within the seed, ovary matures around the seeds. -pollination, fertilization, embryo development within the seed, ovary matures around the seeds. -pollination, germination of pollen, endosperm, ovule. -pollination, endosperm formation, embryo development within the seed, ovule matures.arrow_forward
- What are the external factors on seedling growth? and what are their effects in seed growth and germination? (The seeds used in the experiment are monggo seeds)arrow_forwardWhich suite of reproductive features distinguishes angiosperms from gymnosperms? A. The carpel, double fertilisation, endosperm formation B. Pollen-formation, double fertilisation, seed-formation C. Pollen-formation, the carpel, double fertilisation, endosperm formation D. The carpel, double fertilisation, endosperm formation, seed-formationarrow_forwardIf there is a steep decline in the population of the major pollinators in an area, which of the following angiosperms would be most directly affected: aspen trees, pear trees, or dandelion plants? Why?arrow_forward
