Class 7th
English Project work
1. Collect interesting information related to animal, plants and trees and note down how it behaves. Paste pictures of those animals, trees and plants and prepare your own personal Nature Journal.
2. Pick out all idioms given in your 'Raintree English book' and write their meanings.

plants:
Plants are mainly multicellular organisms, predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, plants were treated as one of two kingdoms including all living things that were not animals, and all algae and fungi were treated as plants. However, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants"), a group that includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, mosses, and the green algae, but excludes the red and brown algae.
animals:
Animals (also called Metazoa) are multicellular eukaryotic organisms that form the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from 8.5 micrometres (0.00033 in) to 33.6 metres (110 ft). They have complex interactions with each other and their environments, forming intricate food webs. The kingdom Animalia includes humans but in colloquial use the term animal often refers only to non-human animals. The scientific study of animals is known as zoology.
trees:
In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world.[1]
NATURE JOURNAL:-
Call for papers: Horticultural plant reproductive biology
Guest editors: Dr. Ray Ming (University of Illinois at Urbana-Champaign), Dr. Li-Yu Chen (Fujian Agriculture and Forestry University), and Dr. Takashi Akagi (Okayama University)
Plant reproduction is an important biological event not only for the propagation of a plant species, more importantly for productivity and quality of crops. The reproductive processes in plants span from the induction of flowering to fruit development and maturation. Horticultural plants provide fruits, vegetables, ornamentals, and beverages for human consumption, most of which are related to the reproductive processes.
Rapid development in genomic, molecular, and synthetic technologies has accelerated discoveries on reproductive biology of horticultural plants. This special issue aims to publish contributions focusing on reproductive biology of horticultural plants, including but not limited to floral induction and floral organ development, sex determination and differentiation, sporogenesis and gametogenesis, pollen-pistil interaction, self-incompatibility, gametophyte interactions and fertilization, embryogenesis and endosperm development, apomixes, fruit and seed development, evolution of reproductive systems, and biotechnological applications in reproduction.
The deadline for submission is March 31, 2021, but the paper can be submitted anytime. Authors interested in contributing should specify "Hort-reproduction” in the cover letter when submitting papers online at the submission system.
