1) Monocots are shorts for “Monocotyledons” which means plants whose embryo has one cotyledon; whereas, Eudicots (Eudicotyledons) carry embryo with 2 cotyledons. The cotyledons of eudicots supply nutrients for seedlings, but the cotyledons of monocots store some nutrients and act as a transfer tissue for nutrients stored elsewhere. Five key features are typically used to distinguish monocots from eudicots; a seed, arrangement of vascular tissue in roots, stems, and leaves, and number of flower parts. The seed has the reproductive structures that are protected from drying out, have male and female gametophytes which are reduced in size. In young dicot stems and stems (usually the upright, vertical portion of a plant transports substances to and the leaves) that do not increase in thickness, xylem and phloem are arranged in vascular bundles in the cortex.
3) What does the taproot system do? Often stores organic nutrients that the plant consumes during flowering and fruit production. 4) Why are root crops such as carrots, turnips, and sugar beets harvested before they flower? Because the taproot system stores organic nutrients in the root part. 5) What is the system where no roots stand out as the main one?
they have two locules. Each locule contains a microsporangium. The tissue between the locules and the cells is called the connective. In an immature, unopened flower bud, the filaments are still short. Their function is then to transport nutrients to the developing pollen.
AP Bio 1982: Brendan Ramos In the life cycle of a fern and a flowering plant, compare and contrast each of the following: A. The gametophyte generation B. Sperm transport and fertilization C. Embryo protection A. Small multicellular male and female gametophytes are produced within the flower of the sporophyte in flowering plants. The gameteophyte of a fern consists of a free-living distinct plant called the prothallus on which structures called archegonia and antheridia produce eggs and sperm respectively.

Examples of fungi are Penicillium, yeast and mushrooms. Plants are multicellular and carry out photosynthesis. The cells are eukaryotic, have cell walls made of cellulose and vacuoles containing cell sap. Also, they have chloroplasts containing photosynthetic pigments. The main plant phyla include mosses, liverworts, ferns and conifers.
This process is called plasmolysis. 11. What cell part did you find around plant cells that you did not find around cheek cells? In general, how does it affect the shape of the
There are 900 mainly perennial species. From plants that are climbers, sub-shrubs, or plants that stems are like bamboo. Begonias vary in characteristics but most have lop- sides, ear- shaped leaves with beautiful markings. The plant flower in clusters with four to five petals. The Begonia was named after Michel Begon (1638-1710).

Contemporary studies focus on molecular variation which is based on variation among DNA nucleotide sequences of the taxa under study. Advancements in the molecular techniques have led to a better understanding of variability within organisms. The genomes of thousands of eukaryotes have been sequenced over the past 25 years, and these data are available in online databases for animals, plants, and fungi. A huge variability is observed in plant genome size. In land plants, nuclear genome sizes differ by a factor of about 1000 fold.
