A grove of trees is a group of trees together, usually without any undergrowth.
Growing is the process of something getting bigger, naturally. Plants and animals start off small and grow as they get older. Animals stop growing when they become an adult while most plants keep growing.
Other things that can grow are crystals and stalactites.
Something is grown if it has finished growing and reached its full size, or has been growing for some time. The dog in the picture is fully grown.
Growth is the process of growing, or something that has recently grown. For example, "look at all the new growth on the trees".
A grub is the immature form of many insects, particularly beetles. Grubs usually live in the ground or in fallen leaves, eating rotting vegetation. The grubs you commonly see in your backyard will grow up to be either beetles or moths. Grubs all look quite similar to each other but can look dramatically different to the adult insect they will turn into.
Scientific name: psidium guajava
