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.
Flowers, dependent embryos, gametangia, vascular tissues, and seeds 87) The key step in adaptation of seed plants to dry land was the evolution of what? wind dispersed pollen 88) What are the two dominant types of seed plants? Conifers and angiosperms 89) What is the male organ in which pollen grains develop? Anther 90) What structure contains spores? A male sporangium 91) What is a stigma in a plant?
Biology Gynoecium: - The gynoecium (from Ancient Greek γυνή, gyne, meaning woman, and οἶκος, oikos, meaning house) is a term with several meanings in botanical usage. In reference to mosses, liverworts and hornworts,gynoecium refers to a cluster of archegonia and any associated modified leaves or stems present on agametophyte shoot. More commonly, gynoecium refers to the ovule-producing part of a flower. The gynoecium is typically the innermost whorl of structures in a flower and is surrounded (in perfect flowers) by the androecium (stamens) and (in complete flowers) by the perianth (petals and sepals). The gynoecium is often inaccurately [clarification needed] referred to as female because it gives rise to female (egg-producing) gametophytes.
Explain what classification is and describe the features found in each kingdom (10) Classification is the assignment of organisms to groups within a system of categories distinguished by structure, origin, etc. The usual series of categories is kingdom, phylum, class, order, family, genus, species. The natural classification used today was devised by the Swedish scientist, Linnaeus. In this scheme, organisms are grouped together according to their basic similarities. A hierarchical system has been devised to distinguish large groups of organisms with a series of rank names to identify the different levels.
SUGAR CANE AND BEGONIAS The main sources for the references gathered in this paper are from the book The Botany of Desire by Michel Pollen. The book focuses on the interactions between people and plants. I will explain how the begonia and sugar cane have changed over the years. How our interactions with these plants have changed us and how we changed the plants. "A Brief History of Sugar."
What is meant by homozygous and heterozygous? Homozygous→ When the alleles from both parent are the same. Heterozygous→ When the alleles from both parents are different. 21. What did Gregor Mendel contribute to the study of biology and what 7 plant traits did he study?
An example would be a cross between two plants with two characters, R and Y. If their genotypes are RRYY and rryy, R can be paired with Y or r and y can be paired with R or Y. 5. What is meant by the terms allele and locus? Make sure to mention homologous chromosomes in your answer.
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.
This happened because the plate was given no bacteria or anything to start growth. 4. The only plate where the E. coli should glow is on the LB/A/X+ plate. The reason for this is that it was the only plate that was given pBlu and no anti-biotic. This causes it to reproduce blue colonies of bacteria.
Genetically modified foods are plants that have had their genetic characteristics altered. 2. What foods can be created by genetic modification? Sweet corn, rice, tomatoes, rape plants, and animals 3. Name 4 examples of genetically modified crops.
