a two-paragraph report on flower reproduction
Answer:
Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. ... Cross-pollination happens when the wind or animals move pollen from one plant to fertilize the ovules on a different plant. The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.
Explanation:
Answer:
Alternation of generations occurs in plants, where the sporophyte phase is succeeded by the gametophyte phase. The life cycle of a flowering plant. The angiosperms were the last of the seed plant groups to evolve, appearing over 100 million years ago during the middle of the Age of Dinosaurs. Reproductive parts of the flower are the stamen and carpel. Often the carpel is referred to as the pistil, the female parts collectively termed the gynoecium. The androecium is the individual units of the androecium are the stamens, which consist of a filament that supports the anther.
Pollen Pollen grains, from the greek palynos for dust or pollen, contains the male gametophyte phase of the plant. The outer part of the pollen is the exine, which is composed of a complex polysaccharide, sporopollenin. Hypothesized steps in the evolution of the carpel. Nonvascular plants, the mosses, and liverworts have the gametophyte phase dominant. Vascular plants show a progression of increasing sporophyte dominance from the ferns and "fern allies" to angiosperms.

Explanation:
Taylor uses a globe as a model to explain why we have day and night on Earth.
Question: How can Taylor complete his model and use it to explain day and night on Earth?
•First, identify one other object needed to complete the model.
•Explain why this object should be included, and suggest how Taylor could represent this object in his model.
•Then, describe how Taylor should move the parts of his model to show the causes of day and night.
•Finally, identify the amount of time this movement would take in the real world.

Euglena, Amoeba and paramecium are unicellular organisms. Euglena moves by flagellates, Amoeba by pseudopods and paramecium moves using cilia.
What are unicellular organisms?Unicellular organisms are lower level organisms having only one cell and an undeveloped nucleus. Most of them are aquatic lives and moves using some special organelles.
Amoeba moves by an arm-like structure emerging from its body and contains microtubules within the arms. Euglena is flagellated microorganism moving by flagella.
Paramecium is an aquatic unicellular microorganism having special whip like structure called cilia which moves it in back forth. Ciliary bodies are like oars to move in a direction.
Therefore, amoeba moves by pseudopodium, euglena moves by flagella's and paramecium moves by cilia.

the punnett square below shows a cross between a pea plant with yellow seeds and a pea plant with green seeds
If mating produces 100 offspring, about how many will have yellow seeds?
A. 25
B. 50
C. 75
D. 100
life iscience 7th grade
Answer:
D
Explanation:
The yellow pea is dominant so if it is crossed with a pure recessive then they will all be yellow
According to Punnett Square, if mating produces 100 offspring, then all of them will have yellow seeds. Thus, the correct option for this question is D.
What is the Punnett Square?The Punnett Square may be characterized as a kind of table in which all of the plausible consequences for a genetic cross between two individuals with known genotypes are systematically demonstrated.
According to the question, there is a homozygous dominant genotype of one parent when crossed with the heterozygous genotype of other parents, then the genotypes of resultant offspring must carry at least one dominant allele which governs the phenotype of the entire offspring.
Therefore, according to Punnett Square, if mating produces 100 offspring, then all of them will have yellow seeds. Thus, the correct option for this question is D.
